A:反应过程中,若增大压强能提高SiCl4的转化率
B:若反应开始时SiCl4为1 mol,则达平衡时,吸收热量为Q kJ
C:若单位时间内生成x molHCl的同时,生成x molH2,则反应达到平衡状态
D:使用过量的H2或升高温度都可以提高SiCl4的转化率
This is my school. There are many trees and flowers in it. The teaching building is big and tall. There is a big playground in our school. After 4:30 in the afternoon, many students come to the playground to play football and some students play table tennis in the table tennis room.There are 1,200 students in 25 classes in our school. The students all like to study. The teachers in our school are very good. They help the students to study and the students like them, too.
