摘要
在介绍阿仑尼乌斯速率方程基础上,从碰撞理论、过渡态理论和托尔曼统计等视角诠释活化能概念,认为仅以活化能大小作依据判断反应速率大小不严密,并从教学层面和试题角度进行了反思.
Based on the introduction of Arrhenius rate equation, this paper explained the concept of activation energy in the perspective of collision theory, transition state theory and Tolman statistics. The results showed that judging reaction rate by only activation energy was imprecise, and analyzed the question from the view of teaching and preparing test questions.
