摘　　要：为了提高反应速率常数和活化能测定实验的准确性,从实验原理和操作步骤等方面进行了探讨,对温差控制、量取器具以及数据处理方法做了改进,让学生在实验中进一步理解活化能的概念并准确测定反应速率常数及活化能,提升了学生的实验操作技能和综合素质,取得了良好的实验教学效果。To improve the accuracy in the determination of reaction rate constant and chemistry activation energy experiment,the experiment principle and operation steps were discussed. Thus,the temperature control,measuring instruments and data processing method have been improved. It will be easier for undergraduate students to understand the concepts of activation energy and to accurately determine the reaction rate constant and activation energy values. The students’ experimental skills and comprehensive qualities have been also enhanced,thus good experiment teaching results have been achieved.
