Abstract To understand the nature of reaction from a qualitative and quantitative perspective, the paper analyzes the 18th question of 2022 Beijing chemistry academic level examination. It aims to help students build balance problem analysis ideas and methods based on the equilibrium constant. And then their awareness and ability can be improved to solve chemical problems using disciplinary thinking methods. According to the industrial production method of “high utilization and low emissions”, this paper analyzes the selection of reagents and helps students experience the creativity and practice of engineers.
