等效平衡是指:同一条件下的同一可逆反应,因起始浓度不同而达到平衡后,任何相同组分的分数(物质的量分数或体积分数)均相同的化学平衡。这类题的解法有以下规律,现推导如下
Equilibrium balance refers to the same reversible reaction under the same conditions. After the equilibrium is reached due to different initial concentrations, the fraction of any identical component (substance fraction or volume fraction) is the same chemical equilibrium. The solution to this type of problem has the following rules and is derived as follows
