根据勒夏特列原理可以推断:对题述平衡体系增大(或减小)压力时,平衡则向右(或向左)移动;重新建立平衡时,氨的浓度要增大(与减小)。而氮及氨的浓度变化情况就较为复杂了。仅依据勒夏特列原理不能做出判断。目前,人们对这个问题的看法截然相反。有人认为两者同时减小(或增大),有人则认为同时增大(或减小)。本文试图对这个问题做一分析,指出结论,供大家讨论。 According to Le Chatelier’s principle, it can be inferred that when pressure is increased (or decreased) on the subject equilibrium system, equilibrium shifts to the right (or left); at equilibrium, the concentration of ammonia increases ). The concentration of nitrogen and ammonia changes in the situation is more complicated. Based solely on Le Chatelier’s principle, no judgment can be made. At present, people have the opposite view on this issue. Some people think that both reduce (or increase), while others think both increase (or decrease). This article attempts to make an analysis of this issue, pointing out the conclusions for your discussion.
