Come to Austria(奥地利)
Soll is a village in the mountains in western Austria. And the Post Hotel is clean and not expensive. It is opened by a local family. From the hotel you can see the whole village, the forests and the mountains. Temperatures in summer are usually 20 to 25 in the daytime, but much cooler by evening.
                                                       
                               Enjoy Thailand!
When you visit Bangkok in Thailand, don’t miss the early morning river boat trip to the Floating(漂浮) just outside the city. There you will find many kinds of fruits and vegetables. And you can pay for them when you sit in your boat. Don’t forget your hat: the sun can be strong and it may be as hot as 40 at noon.
 
                               Visit Hawaii!
Maybe the most beautiful place in Hawaii is Kauai. You can visit its long, sandy beaches in the south and west of the island, and mountains and forests in the north, but don’t be surprised if it rains in the centre of the island. Daytime temperatures there are usually around 24 to 26 by the sea, and only a little cooler by late evening.

题型:填空题

2013年雾霾天气多次肆虐我国中东部地区。其中,汽车尾气和燃煤尾气是造成空气污染的原因之一。

(1)汽车尾气净化的主要原理为:2NO(g)+2CO (g)2CO2 (g) +N2 (g)在密闭容器中发生该反应时,c(CO2)随温度(T)、催化剂的表面积(S)和时间(t)的变化曲线,如图所示。据此判断:

①该反应的平衡常数表达式为   

②该反应的ΔH   0(选填“>”、“<”)。

③当固体催化剂的质量一定时,增大其表面积可提高化     学反应速率。若催化剂的表面积S1>S2,在图中画出c(CO2)在T2、S2条件下达到平衡过程中的变化曲线。

(2)直接排放煤燃烧产生的烟气会引起严重的环境问题。

① 煤燃烧产生的烟气含氮的氧化物,用CH4催化还原NOx可以消除氮氧化物的污

染。

CH4(g)+2NO2(g) = N2(g)+CO2(g)+2H2O(g) =-867kJ·mol1

2NO2(g)  N2O4(g)                    =-56.9kJ·mol1

写出CH4催化还原N2O4(g)生成N2(g)、CO2(g)和H2O(g)的热化学方程式   

②将燃煤产生的二氧化碳回收利用,可  达到低碳排放的目的。下图是通过光电转化原理以廉价原料制备新产品的示意图。写出上述光电转化过程的化学反应方程式                     。催化剂a、b之间连接导线上电子流动方向是        (填a→b或b→a) 。
