一、等效平衡的含义化学平衡状态的建立与条件有关,与途径无关。建立平衡状态的途径通常有4条:①正向建立,②逆向建立,③从中间某状态建立,④反应物分批加入建立。一定条件下,只是起始状态不同的同一可逆反应达到平衡后,任何相同组分的分数(体积、物质的量)均相同,这样的化学平衡互称为等效平衡。等效平衡包括两种情况,一是两个平衡状态完全相同的等同平衡,二是同种物质的百分含量相同,但其物质的量不同的两个平衡体系。二、等效平衡的判断和特征等效平衡的判断方法可从两个角度进行,从起始 First, the meaning of equivalent equilibrium The establishment of chemical equilibrium state and the conditions, has nothing to do with the way. There are usually four ways to establish a balance state: ① positive establishment, ② reverse establishment, ③ establishment from a certain intermediate state, ④ reactant added in batches. Under certain conditions, only the same reversible reaction with different initial states reaches equilibrium, and the scores of any of the same components (the volume and the amount of substances) are the same, and the chemical equilibriums are mutually equivalent equilibria. Equivalent balance includes two cases, one is the same balance between the two equal balance, the second is the same percentage of the same substance, but the amount of material in two different balance system. Second, the equivalent balance of judgment and characteristics Equivalent balance of judgment can be carried out from two perspectives, from the beginning
