摘　　要：化学热力学、动力学是无机化学和物理化学课程的重要内容,然而这部分知识抽象难懂。我们尝试在教学中将计算模拟与化学热力学、动力学知识点深度融合,帮助学生加深对知识的理解。在课堂上通过向学生模拟演示甲醛解离反应的化学热力学和动力学过程,将抽象知识直观、可视化。根据学生反馈发现后续课堂学生的积极性、参与度都有很大的提高。Chemical thermodynamics and kinetics are the important contents in the course of inorganic chemistry and physical chemistry,but this part of knowledge is difficult to understand.We tried to integrate the computational simulation with the knowledge of chemical thermodynamics and dynamics in order to help students understand the knowledge.In the class,we demonstrated students with the chemical thermodynamics and kinetics process of formaldehyde dissociation reaction,so as to make the abstract knowledge intuitive and visual.According to the students’feedback,we found that the enthusiasm and participation of the students in the subsequent class have been greatly improved.
