Abstract: The teaching of chemical kinetics in physical chemistry is centered on catalytic reaction science, which discusses simple methods for determining important kinetic parameters (reaction rate, reaction order, reaction activation energy, etc.) in chemical kinetics in the experimental process of catalytic reaction. In the teaching, the mechanism of catalytic reaction is analyzed and discussed. And the basic theoretical knowledge in the textbook is combined with practical application, which expands students' thinking, enhances students' enthusiasm for learning, and improves students' learning efficiency and innovation ability.
