摘　　要：针对现行教材中由电极电势求化学反应平衡常数的计算公式缺少详细说明而易引起学生误会乱用的问题,本文分别从应用公式的前提条件、须与化学反应计量式相对应和应用公式的适当拓展等三个方面,以例题的形式逐一展开讨论,旨在帮助学生加深理解公式的内涵,提高准确应用知识解决实际问题的能力。Many students are easy to misunderstand and misuse the calculation formula regarding standard electrode potential and standard equilibrium constant due to lack of explications for it in available textbooks.In this paper,the formula is explicated,in the form of resolving examples from three perspectives-the conditions for using it,appropriate stoichime-tric equation and exdension,in order to assist students to comprehend the formula and enhance their ability to resolve practical problems through correspouding knowledge.
