化学平衡这一基本理论是高考的常考题目,但大多数考生都感觉化学平衡中的“等效平衡计算”是一个难点,无从下手.笔者经过多年总结,认为采用“5步突破法”解决此类问题非常简单和快捷.这5步分析过程是指:1)审题:首先要明确可逆反应建立平衡的外界条件——恒温、恒压,还是恒温、
The basic theory of chemical equilibrium is the college entrance examination often exam topics, but most of the candidates feel chemical equilibrium in the “equivalent balance calculation” is a difficult, can not start. The author after years of summary, that the use of “five-step breakthrough” solution This kind of question is very simple and quick.The analysis process of this 5 steps refers to: 1) examining the question: Must clear the reversible reaction and establish the balanced external condition at first - constant temperature, constant pressure, or constant temperature,
