Abstract This paper used instruments such as homemade wooden fixer, syringe to design experiment device, used pressure sensor to show the effect of pressure on chemical equilibrium "2NO2?N2O4". This experiment was easy to operate, and the equilibrium movement process was displayed intuitively, it was very helpful for students to learn the chemical equilibrium, especially the understanding of Le Chatelier's principle.
