很多学生对气体可逆反应中的等效平衡问题感到难以判断和理解.本人在实际教学中感受到,这类问题若从它们的反应条件入手将较易解决.一、恒温定容时的等效平衡1.对于反应前后气体分子数不相等的反应来说,起始虽然以不同方式投料,但不同情况下,若各 Many students find it difficult to judge and understand the problem of equivalent balance in gas reversible reactions. I feel in practical teaching that such issues will be easier to solve if they start from their reaction conditions. I. Equivalent at constant temperature and constant volume Equilibrium 1. For reactions where the number of gas molecules is not equal before and after the reaction, the initials are fed in different ways, but in different cases, if
