化学反应速率和化学平衡中的概念比较抽象,不好理解,笔者在教学实践中发现巧妙使用类比,可以使复杂问题变得简单易懂,学生乐于接受且效果明显,下面举几例加以说明。一、化学反应速率方面1.反应速率快慢的比较例1可逆反应2A(g)+B(g) The concept of chemical reaction rate and chemical balance is rather abstract, not easy to understand, the author found ingenious use of analogy in teaching practice, can make complex problems become easy to understand, students are willing to accept and the effect is obvious, to give a few examples to illustrate. First, the chemical reaction rate 1. Reaction rate of the comparative example 1 reversible reaction 2A (g) + B (g)
