我们在学习化学平衡理论时知道,不论反应的起始浓度如何,也不论是从正反应开始还是从逆反应开始,最后都能达到一定条件下的平衡。那么什么是等效平衡呢?在同一条件下的同一可逆反应,由于起始浓度不同可形成多个不同的平衡体系。其中平衡混合物的百分组成相同,各物质的浓度也分别相同的两个或若干个平衡体系,可称为等效平衡,等效平衡中反应进行的程度是一样的。 When we learned the theory of chemical equilibrium, we knew that regardless of the initial concentration of the reaction, whether it was from the start of the positive reaction or the start of the reverse reaction, we could reach equilibrium under certain conditions. So what is the equivalent balance? In the same reversible reaction under the same conditions, different equilibrium systems can be formed due to different initial concentrations. Among them, two or several equilibrium systems in which the equilibrium composition has the same percentage composition and the concentrations of the respective substances are the same, may be referred to as equivalent equilibriums, and the degree of reaction performed in the equivalent equilibrium is the same.
