化学反应速率和化学平衡是中学化学中的一个重要的知识点 ,特别是化学平衡又是中学化学教学的难点 ,同时也是历年高考试题中必考的热点。从近十多年涉及此类问题的高考试题来看 ,主要有以下几种类型 :一、化学反应速率题化学反应速率是用来衡量化学反应进行的快慢的。有关内容 Chemical reaction rate and chemical balance are an important knowledge point in middle school chemistry. In particular, chemical balance is also a difficult point in chemistry teaching in middle schools. It is also a hot spot in the high examination questions of previous years. From the high exam questions involving such issues in the past decade or so, there are mainly the following types: First, the chemical reaction rate The chemical reaction rate is used to measure the speed of the chemical reaction.
