摘　　要：旋光度法测定蔗糖水解速率常数是大学物理化学实验中最常见的实验项目之一。本文对该实验项目的教学内容进行了深入讨论,充分利用实验数据,获得了该反应的正、逆反应速率常数及反应平衡常数的计算,拓展了化学反应动力学相关的微观认识。To determine the rate constant of sucrose hydrolysis using rotation spectrophotometry is one of the most common experimental projects in university physical chemistry experiments. The experiment content has been developed through in - depth discussions about the experimental result. The positive and reverse reaction rate constant and the reactive equilibrium constant can be obtained by making full use of the experimental data. Some microscopic understanding relating chemical reaction kinetics has been excavated.
