Equilibrium balance problem is not only a key point in the review of college entrance examinations, but also a difficult point in teaching. This article analyzes the twenty-sixth problem of the college entrance examination chemistry test in Jiangsu Province in 2003, and summarizes the general laws to solve the problem of equivalent balance. . For your colleagues in the teaching reference. Problem I. Under constant temperature and constant pressure, the following reaction occurs in a variable volume container: A(g) + B(g) C(g)1 if
