試題詳情

高三化學攻關三十六法之――平衡結(jié)果求取值

 

通常是由起始數(shù)據(jù)求平衡結(jié)果,反其道則難度增加,若由平衡結(jié)果求取值范圍,則更難。

●難點磁場

請試做下列題目,然后自我界定學習本篇是否需要。

若273 K下,某容器容積為10.0 L,容器內(nèi)存在如下平衡:

2NO2+4SO2 4SO3+N2

各物質(zhì)起始量分別是:NO2:2.0 mol、SO2a mol、SO3:4.0 mol、N2:1.2 mol;平衡時容器內(nèi)氣體的總物質(zhì)的量8.0 mol。只要a的取值合理,按上列數(shù)值投料平衡就不會發(fā)生移動,此時a          。

●案例探究

[例題]在一個容積固定的反應器(如圖19―1)中,有一可左右滑動的密封隔板,兩側(cè)分別進行如圖19―1所示的可逆反應。各物質(zhì)的起始加入量如下:A、B和C均為4.0 mol、D為6.5 mol、F為2.0 mol,設E為x mol 。當x在一定范圍內(nèi)變化時,均可以通過調(diào)節(jié)反應器的溫度,使兩側(cè)反應都達到平衡,并且隔板恰好處于反應器的正中位置。請?zhí)顚懸韵驴瞻祝?/p>

 

圖19―1

 

(1)若x=4.5,則右側(cè)反應在起始時向           (填“正反應”或“逆反應”)方向進行。欲使起始反應維持向該方向進行,則x的最大取值應小于___________。

(2)若x分別為4.5和5.0,則在這兩種情況下,當反應達到平衡時,A的物質(zhì)的量是否相等?___________(填“相等”“不相等”或“不能確定”)。其理由是                       。

命題意圖:化學平衡移動考題,以前是求x的某一個具體數(shù)值,本題是求x的一個范圍,這主要是對學生創(chuàng)新思維能力的考查。

知識依托:勒夏特列原理。

錯解分析:通常平衡計算題是已知起始量求平衡結(jié)果,本題反其道而行之,已知平衡結(jié)果,求起始量的取值范圍,增大了試題難度,結(jié)果:(1)不少學生不會解。(2)問答錯的主要原因是忽視了左右兩容器內(nèi)溫度相同這一客觀條件。

解題思路:(1)由于左側(cè)反應為氣體物質(zhì)的量不變的反應,無論平衡如何移動,左側(cè)氣體總物質(zhì)的量總是:4.0 mol+4.0 mol+4.0 mol=12.0 mol。當x=4.5時,反應起始時右側(cè)氣體總物質(zhì)的量為:6.5 mol+4.5 mol+2.0 mol=13.0 mol。要使隔板位于反應器中間,右側(cè)反應最終結(jié)果必須是:氣體物質(zhì)的總物質(zhì)的量與左側(cè)相等,即12.0 mol;這樣,右側(cè)反應必須向氣體物質(zhì)的量縮小的方向,即該反應的正反應方向移動(評注:原題中說成:“右側(cè)反應起始時向××方向進行”是不確切的,因為只要可逆反應一開始,就會同時向正、逆兩個反應方向進行)

下面求x的最大取值。

方法①(列方程法):設達到平衡時,D的物質(zhì)的量消耗 a mol,則:

D(g)              +    2E(g)  2F(g)

n                    6.5 mol          x mol             2.0 mol

n            (6.5-a) mol      (x-2a)mol     (2.0+2a)mol

(6.5-a)mol+(x-2a)mol+(2.0+2a)mol=12.0 mol

那么,    (6.5-a)mol>0 mol

      (x-2a)mol>0 mol

解得:x<7.0

方法②(極限思維):由于起始時反應向正方向進行,則它的極限結(jié)果是nD=0或nE=0,二者具其一或其二,這時x可取最大值。

D(g)              +           2E(g)  2F(g)

n                    6.5 mol                 x mol             2.0 mol

極限①    0 mol                    (x-13)mol     15 mol

極限②    (6.5-x/2) mol              0 mol             (2.0+x)mol

由極限①得:(x-13)mol+15 mol=12.0 mol,解得:x=10,此時:nE=(x-13) mol=-3 mol,顯然不合題意,應舍去。

由極限②得:(6.5-x/2)mol+(2.0+x)mol=12.0 mol,解得:x=7.0 mol,可見,x的最大極限為7.0,即x<7.0,因為當x=7.0時,nE=0 mol,顯然不合題意。

(2)只要注意題設:“x在一定范圍內(nèi)變化時,均可以通過調(diào)節(jié)反應器的溫度,使兩側(cè)反應都達到平衡,…!憋@然,當x=4.5和5.0時,右側(cè)反應的溫度是不一樣的,那么,整個反應器的溫度也是不一樣的,這對于左側(cè)反應來說,是在不同的溫度下建立的平衡,A的物質(zhì)的量是不相等的。

答案:(1)正反應   7.0

(2)不相等      因為這兩種情況是在兩個不同溫度下達到化學平衡的,平衡狀態(tài)不同,所以A物質(zhì)的量不相同

●錦囊妙計

由平衡結(jié)果求取值有兩種方法:

1.列方程法:根據(jù)反應移動的方向,設出某反應物消耗的量,然后列式求解。

2.極限思維:有口訣如下:

始轉(zhuǎn)平、平轉(zhuǎn)始,欲求范圍找極值。

極限思維是解此類問題的常用方法。

●殲滅難點訓練

1.(★★★)題設同例題,求右側(cè)平衡不移動時x的取值。

 

 

 

2.(★★★★)題設同例題,求右側(cè)平衡起始時向逆反應方向移動的x的取值范圍。

 

 

 

3.(★★★★)若nD=3.0 mol,不論平衡如何移動,其他條件同例題,求x的取值范圍。

 

 

 

 

4.(★★★★★)在某條件下,容器中有如下平衡反應:

A+4B  2C+D(正反應放熱)

此時,A、B、C的物質(zhì)的量均為a mol,而D的物質(zhì)的量為d mol。

(1)改變a的取值,再通過改變反應條件,可以使反應重新達到平衡,并限定達到新的平衡時,D的物質(zhì)的量只允許在d/2到2d之間變化,則a的取值范圍            (用ad的關系式表示)。

(2)如果要使本反應重新建立的平衡中,D的物質(zhì)的量只允許在d到2d之間取值,則應該采取的措施是              (從下面列出的選項中選擇)。

A.升高反應溫度                                       B.增大反應容器內(nèi)之壓強

C.增大反應容器容積                                D.降低反應溫度

E.減小反應容器內(nèi)之壓強                         F.減小反應容器容積

At that time, typewriters used a carbon film ribbon(打字機色帶),and it was hard to correct typing   33   on the paper. Graham found a   34   way. She decided that she would do what painters did to   35   their mistakes ― paint over them. She took her water-based paint to work,   36   a brush.

Her boss never   38   the mistakes. When another secretary asked for some of her   39   correcting liquid, Graham found a bottle at home, wrote "Mistake Out" on a label, and gave it to her.   40   all the other secretaries in the building wanted some, too.

By 1956, Graham’s invention became so   41   that she turned her kitchen into a laboratory and made bottles of “Mistake Out” using her electric mixer. When   42   grew, Graham changed the name of “Mistake Out” to “Liquid Paper” and   43   a patent and trademark

Ⅳ.閱讀理解(共20小題,每題2分,滿分40分)

A

Students who say they never or hardly ever used dictionaries may speak English well but usually write poorly, because they make many mistakes.

    The students who use dictionaries most do not learn especially well either. The ones who look up every new word do not read fast. Therefore they do not have time to read much. Those who use small two-language dictionaries have the worst problems. Their dictionaries often give only one or two words as translations of English. But one English word often has many translations in a foreign language and one foreign word has many translations in English.

    The most successful students are those who use large college edition dictionaries with about 100,000 words but do not use them too often. When they are reading, these students first try to get the general idea and understand new words from the context. Then they reread and use the dictionary to look up only key words that they still do not understand. They use dictionaries more for writing. If they are not sure how to spell a word, they always use a dictionary. Also, if they think a noun might have an unusual plural form, they check this in a dictionary.

51.According to the passage, which of the following is WRONG?

   A. Dictionaries have little effect on learning to speak English.

   B. Whatever new words you meet while reading, never use dictionaries.

   C. Small two-language dictionaries have serious shortcomings.

   D. Reading something for the first time, you’d better not use dictionaries.

52.This passage mainly tells us        .

   A. that students shouldn’t use small two-language dictionaries

   B. what were the shortcomings of small two-language dictionaries

   C. why students should use large college edition dictionaries

   D. what dictionary students should choose and how to use it

53.Which is NOT mentioned in this passage?

   A. How to make good use of a dictionary.  B. When to use a dictionary.

   C. How to improve spoken English.                  D. How to practice reading fast.

 

B

When she looked ahead, Florence Chadwick saw nothing but a solid wall of fog. Her body was numb(全身麻木). She had been swimming for nearly sixteen hours. Already she was the first woman to swim the English Channel in both directions. Now, at age 34, her goal was to become the first woman to swim from Catalina Island to the California coast.

On that fourth of July morning in 1952, the sea was like an ice bath and the fog was so dense she could hardly see her support boats. Sharks cruised toward her lone figure, only to be driven away by rifle shots. Against the cold sea, she struggled on ---- hour after hour ---- while millions watched on national television.

Alongside Florence in one of the boats, her mother and her trainer offered encouragement. They told her it wasn't much farther. But all she could see was fog. They urged her not to quit. She never had … until then. With only a half mile to go, she asked to be pulled out.

She told a reporter hours later, "Look, I'm not excusing myself, but if I could have seen land I might have made it." It was not tiredness or even the cold water that defeated her. It was the fog. She was unable to see her goal.

Two months later, she tried again. This time, despite the same dense fog, she swam with her goal clearly pictured in her mind. She knew that somewhere behind that fog was land and this time she made it! Florence Chadwick became the first woman to swim the Catalina Channel, eclipsing(超出) the men's record by two hours!

54.Florence Chadwick was the first woman to swim across ________.

A. the English Channel                                               B. the Catalina Channel  

C. the California coast                                                 D. Catalina Island

55.Florence failed on her first trial mainly because of _______.

    A. the sharks                   B. the tiredness             C. the cold water       D. the bad weather

56.The underlined word “then” in this passage refers to the period when _______.

A. she had swum nearly sixteen hours               B. sharks swam toward her

C. she couldn’t see her support boats                D. millions of people watched her on TV

57.We can infer from the passage that it was ______ that resulted in her success.

A. her family’s encouragement    B. her iron will    C. her swimming skills   D. the good weather

The Museum of Childhood is spread over 4 floors, with the first floor acting like a balcony around the edge of the building, so you can look down over the ground floor central hall with the shop, Information Desk and Benugo Café.

The museum of Childhood is housed in a large Victorian building in east London. It has been on this site since 1872. It has undergone refurbishment (翻新) and reopened in 2006 and an elevator now makes all floors accessible.

This is not a quiet place and children are allowed to have fun here. Child safety is extremely important and a member of staff remains by the front door at all times. Also, note the “Code of Behavior” notice, which includes: children under 12 must be supervised by an adult; no eating in the galleries and no running.

Toy exhibits are in glass cases and there are plenty of low-level exhibits for younger children to see. The glass cases have lots of thought-inspiring questions on them to encourage discussion between adults and children. When you or the children need some quiet time, there are sofas at either end of the second floor with reading books available.

Pros: Many free activities for kids

Cons: Can be too warm inside

Visit Duration: 1.5 hours

Opening Hours: 10:00 a.m. ? 5:45 p.m.  Last admission is 5:30 p.m.

The Museum is closed on 25 and 26 December and 1 January every year.

Admission: Admission the Museum is free. There is a small charge for some activities.

58.In the Museum of Childhood, _______.

A. people can reach any floor by elevator         B. there are sofas at either end of the first floor

       C. there are exhibits on the museum history      D. the Information Desk can be found on each floor

59.The Museum of Childhood may be attractive to _______.

       A. parents who only have children under 12      B. children who are fond of toy exhibits

       C. parents and children who need quiet time      D. kids who like playing games with their parents

60.What is the disadvantage of the museum?

       A. Low-level exhibits are too boring.              B. Children may feel slightly hot in it.

       C. Parents have to stay with their kids.             D. No staff members attend to the kids.

61.What information can we get about the museum?

      A. All the activities for children are free.          B. The museum is located in west London.

       C. Children are allowed to enter after 5:30.       D. The museum is unavailable on Christmas Day.

A quick look at the lengths of children’s index and ring fingers can be used to predict how well students will perform in education tests, new research claims.

Kids with longer ring fingers compared to index fingers are likely to have higher math scores than literacy or verbal scores in the entrance exam for primary school, while children with the reverse finger-length ratio are likely to have higher reading and writing, or verbal, scores versus(與......相對) math scores.

Scientists have known that different levels of the hormones testosterone(雄性激素)and estrogen (雌性激素) in the womb(子宮) account for the different finger lengths, which are a reflection of areas of the brain that are more highly developed than others, said psychologist Mark Brosnan of the University of Bath in Britain, who led the study.

Exposure to testosterone in the womb is said to promote development of areas of the brain often associated with spatial(空間的) and mathematical skills, he said. That hormone makes the ring finger longer. Estrogen exposure does the same for areas of the brain associated with verbal ability and tends to lengthen the index finger relative to the ring finger.

To test the link to children's scores on the Scholastic Assessment Test, Brosnan and his colleagues made photocopies of children's palms and measured the length of their index and ring fingers. They used the finger-length ratios as a proxy(參照指標) for the levels of testosterone and estrogen exposure.

    The researchers then looked at boys' and girls' test performances separately and compared them to finger-length ratio measurements. They found a clear link between high prenatal testosterone exposure, indicated by the longer ring finger compared to the index finger, and higher scores on the math SAT.

Similarly, they found higher literacy SAT scores for the girls among those who had lower prenatal testosterone exposure, as indicated by a shorter ring finger compared with the index finger.

62.It’s likely that if a Chinese child with a longer index finger than his ring finger, he will probably get good marks in ______.

A. math                          B. physics                        C. chemistry                                D. Chinese 

63.The underlined word “reverse” in Paragraph Two probably means_______.

A. similar                       B. opposite                     C. indifferent                              D. strange

64.What can make your index finger longer than your ring finger according to the research?

A. Estrogen.                    B. Testosterone.               C. Vitamin.                                  D. Vegetables.   

65.Which of the following statements is NOT correct in the passage?

One possible student version:

There are various ways for us middle school students to share opinions with each other. One way is to hold discussions, where we can freely exchange our views. We can also make use of the phone and the Internet. Making phone calls is very convenient, yet sending messages is more popular among us. Sometimes, we can send each other emails, in which more information can be included and we can express our opinions more clearly.

Personally, I think talking face to face is the best way to share opinions. In this way, I can express myself more comfortably. Meanwhile, I can sense how others feel and learn what they think. With the help of body language, I can make myself better understood.

M: Gardening's too much like hard work for me. If I have time to spare, I like to play ten­nis or go for long country walks.

W: Well, I think of gardening as play, not as work. I'm never as happy as when I’m busy in the garden.

Text 2

W: When is our plane to take off?

M: At half past five.

W: Oh dear! That only leaves us 15 minutes to go through customs and check our baggage.

Text 3

W: What a hot day! Do you always have weather like this in May?

M: Generally it's much better than this. And I can't remember when we had such a rainy day.

Text 4

W: To teach those students English, do you have to speak their language quite well?

M: No. quite the contrary. They benefit most when the class is organized entirely in the foreign language.

Text 5

W: Americans tend to think from the particular and small to the general and large.

M: For example?

W: We've just seen an example of this in the fact that they progress from personal and local matters to the state and finally the nation ― not the other way around.

Text 6

M: This machine drives me mad.

W: How come?

M: Well, most of the time, it's fine. I rent a movie and I put it in and press ON. But the other day, I wanted to program it, like, to record a show. So, I read the directions. And I followed them exactly, you know, step by step, but then, nothing. It didn't record.

W: Is there anything wrong with the machine?

M: With the machine? No. There’s something wrong with me. I’m no good with, like, electronic equipment.

Text 10

M: Good morning, and I'd like to welcome all of you to the University of North Carolina. This is the oldest public university in the United States, and we are proud to say that we offer one of the best public education opportunities anywhere in the nation. The school started in 1792, and has been open ever since, with the exception of having been closed for two years in the 1860s because so many young men left to fight in the Civil War. Following the war, the university opened its doors again and has been open ever since. In this century, the student number has been increasing rapidly, including women and small groups. Now we are looking forward to a bright future where students from all backgrounds attend this university. Thank you.
