等效平衡是高中化学学习的难点,但是也是高中化学必须掌握的知识点.在化学考试中会出现各种关于等效平衡的难题,如何有效解决等效平衡题呢?本文试图从认识等效平衡、等效平衡的分类和解决有效平衡的方法去探讨等效平衡问题.一、认识等效平衡1.概念在一定条件(恒温恒容或恒温恒压)下,同一可逆反应体系,不管是从正反应开始,还是从逆反应开始,在达到化学平衡状态时,任何相同组分的含量(体积分数、物质的量分数等)均
Equivalent balance is the difficulty of high school chemistry learning, but it is also the knowledge that high school chemistry must master.In the chemistry test, there will be a variety of problems about the equivalent balance, how to effectively solve the problem of equivalent balance? This article attempts to understand from the equivalent Equilibrium, equivalent equilibrium classification and effective balance method to explore the issue of equivalent balance.An understanding of the equivalent balance 1. Concept Under certain conditions (constant temperature or constant temperature and pressure), the same reversible reaction system, either From the beginning of the normal reaction, or from the beginning of the reverse reaction, the content of any of the same components (volume fraction, mass fraction, etc.) reaches the state of chemical equilibrium
