一级反应网络动力学模拟软件及其在教学中的应用

Kinetics Simulation Software of First-order Reaction Network for Teaching

在化学动力学和物理化学等相关课程的教学过程中,通常会涉及一级复合反应或一级反应网络,其规律复杂,比较难以理解。通过使用可视化的Visual Basic语言编写的一级反应网络动力学模拟程序,反应组分数和反应条件可以随意输入,可以直观地模仿实验条件的改变对反应各组分浓度随时间的变化规律。通过教学实践表明,学生更容易掌握化学动力学的相关规律。

In the teaching processes such as Chemical Kinetics and Physical Chemistry courses,the contents related to first-order composite reactions and reaction network are usually difficult to understand. A numerical simulation program for the kinetics of first-order reaction network was developed using visual basic language. The component numbers and reactive conditions can be easily changed and the concentrations of each species can be quickly calculated and showed in a graph.The teaching practices showed that the applications for this program can promote the understanding of chemical kinetic rules.
