有关等效平衡的题目学生解起来往往感到无从下手,现将常见此类题型剖析如下:等效平衡的定义:在条件不变时,可逆反应不论采取何种途径,即无论从正反应开始还是由逆反应开始,最后所处的平衡状态是相同的(各组分的百分含量相同)等效平衡题常用的解法——极值法 The problem of equivalent balance is often explained by the students who have no way of starting to understand. Such common types of questions are now parsed as follows: Definition of Equilibrium: When conditions do not change, the reversible reaction no matter what approach is adopted, that is, whether it starts from positive reaction. It also starts from the reverse reaction, and the last equilibrium state is the same (the percentage of each component is the same). The commonly used solution to the equivalent equilibrium problem is the extremum method.
