已知298K时，反应N2（g）＋3H2（g）2NH3（g）ΔH＝-92.2kJ・mol-1  ΔS＝-198.2J・mol-1・K-1。请分析，298K时，合成氨反应能否自发进行。 答案：（1）由于ΔH-TΔS＝-92.2kJ・mol-1-298K×（-198.2×10-3kJ・mol-1・K-1）＝-33.14kJ・mol-1＜0，因此，298K时，合成氨反应能自发进行。 根据句意及各题括号中所给的汉语意思，从下面的方框中选择合适的单词或词组，用其适当形式填空。 1．The island is ________(进入)only by boat． 2．Our car had a ________(故障)on the road． 3．Did he give you ________(许可)to take that? 4．One of the main ________(弊端)of the system is that it uses very large amounts of fuel． 5．If you need any help, don't ________(犹豫)to call us． 6．The ________(显示器)is the part of the computer that looks like a television． 7．This book ________(包含)lots of useful information． 8．The car ________(碰撞)into a tree and burst into flames． 9．Buses run ________(经常地)from the city to the airport． 10．Lamp is one of Edison's ________(发明)． 11．East Timor was formally declared ________(独立)in(2001． 12．The employees' ________(平均)income in this company is about $1500 a month． 13．You can ________(登录)on this website to look for the information． 14．There should be ________(保护)systems in your computers against viruses． 15．Government should ________(创造)more job opportunities for us． 16．I can operate a computer ________(也)． 17．The government tries its best to make prices ________(下降)． 18．Who ________(提出)an idea to put back the hours in summer? 19．I'm ________(设计)a garage for my new car． 20．As a student, you should ________(集中)on your study．
