Abstract On the basis of the improved micro-experiment of chemical reaction rate determination and the principle of situational similarity, the experimental data were developed into a simulation experimental software. It helps to determine the simulated chemical reaction rate, record, analyze and integrate data and draw images in classroom teaching. In the context of similar situation, students are allowed to experience the process of scientific research, explore the teaching value of chemical experiment data analysis, understand and establish the relation of v=Δc/Δt and understand the source of various change curves.
