图像题是化学平衡中的常见题型,是勒沙特列原理等化学平衡知识在直角坐标系中的直观反映.同时,它又是化学平衡的重点、难点,学生的疑惑点、失分点.怎样解决有关图像问题呢?一、图像题的类型1.速率-时间图此类图像定性揭示了v(正)、v(逆)随时间(含条件改变对速率的影响)而变化的 The image problem is a common problem in chemical equilibrium and is an intuitive reflection of the knowledge of chemical equilibrium in the Cartesian coordinate system such as the principle of Le Sate column. At the same time, it is also a key point of chemical equilibrium, a difficult point, and a doubt point of students. How to solve the image problem? First, the type of image problem 1. Rate - Time Figure Such images qualitatively reveal v (positive), v (inverse) with time (including changes in the rate of impact) changes
