已知：反应I：4NH₃（g）+6NO（g）⇌5N₂（g）+6H₂O（l）△H₁

反应Ⅱ：2NO（g）+O₂（g）⇌2NO₂（g）△H₂（且|△H₁|=2|△H₂|）

反应Ⅲ：4NH₃（g）+6NO₂（g）⇌5N₂（g）+3O₂（g）+6H₂O（l）△H ₃

反应I和反应Ⅱ在不同温度时的平衡常数及其大小关系如下表

（1）△H₃=____ （用△H₁、△H₂的代数式表示）；推测反应Ⅲ是____ 反应（填“吸热”或“放热”）

（2）相同条件下，反应I：4NH₃（g）+6NO（g）⇌5N₂（g）+6H₂O（l）在2L密闭容器内，选用不同的催化剂，反应产生N₂的量随时间变化如图所示．

①计算0～4分钟在A催化剂作用下，反应速率V_（NO）=____ ．

②下列说法不正确的是____ ．

A．单位时间内H﹣O键与N﹣H键断裂的数目相等时，说明反应已经达到平衡

B．若在恒容绝热的密闭容器中发生反应，当K值不变时，说明反应已经达到平衡

C．该反应的活化能大小顺序是：E_a（A）＞E_a（B）＞E_a（C）

D．增大压强能使反应速率加快，是因为增加了活化分子百分数

（3）一定条件下，反应II达到平衡时体系中n（NO）：n（O₂）：n（NO₂）=2：1：2．

①保持恒温恒容，再充入NO₂气体，NO₂体积分数____ （填“变大”、“变小”或“不变”）

②关于平衡体系反应Ⅱ：2NO（g）+O₂（g）⇌2NO₂（g）；△H₂说法正确的是____ ．

A、该反应焓变为负值

B、升高温度，逆反应速率增大，正反应速率减小，反应逆向移动

C、不论增大压强还是减小压强，正方向速率改变的程度更大

D、平衡正向移动，NO的转化率一定增大

E、平衡体系中加入NO₂，平衡逆向移动，△H₂减小

F、混合气体颜色加深说明平衡向右移动，颜色变浅则向左移动．

    You might be surprised to learn that India produces about 800 movies a year, and that number continues to grow. Just as the center of the American film industry is Hollywood, the movie center of India is Mumbai, known 1 Bombay. “Bollywood” is a combination (结合) of the 2“Bombay”and“Hollywood”.

    Bollywood is not a physical place. Some people 3 the name, saying that it makes the industry look like a poor cousin to Hollywood.4 ，Bollywood is one of the largest centers of film production in the world.

    No Bollywood movie is thought complete 5 a few songs and dances. In fact, music is an important part of Bollywood movies. Even a bad movie can still be 6 if the music is good. Because of this, music directors are sometimes more popular than actors. A Bollywood movie has five to six songs in it, often explaining what the dances mean. A film's success often 7 on the quality of such musical numbers. In some ways, Bollywood has been influencing 8 films in the western world since the 2000s.

    Bollywood may be different from Hollywood when it comes to musical style, but it is very 9 to Hollywood in several ways. Bollywood hero Shark Khan uses a gun just like Hollywood star Tom Cruise. News reporters follow Bollywood stars just as often as Hollywood stars. The personal lives of Indian actors and actresses catch the headlines, just as 10 do in the United States.
