活化能的概念在高一化学中是一个比较重要但又不易讲清的概念。这个概念的定义本身较难理解,要讲好它,涉及到许多内容,若安排不当,往往不能收到良好的效果。以下谈谈我在教学中的做法。一、活化能。在按教材的顺序讲解中,首先突出讲清分子(或离子)间的互相接触、 The concept of activation energy is a more important but difficult to clarify concept in Chemistry. The definition of the concept itself is more difficult to understand. To explain it well, it involves a lot of content. If it is improperly arranged, it often fails to receive good results. Let’s talk about my practice in teaching. First, activation energy. In the explanation of the teaching materials, the first step is to highlight the contact between the molecules (or ions)
