无机化学教学中,应用热力学讨论有关问题,在我国还只是近几年才开始。热力学的引入,对我们讨论有关问题,如化学反应的方向和限度问题,化合物的热力学稳定性问题等,无疑带来了很大的方便,因而颇受欢迎。但是出于无机化学本身的教学要求和限制,不可能对引入的热力学问题进行详细,透彻地介绍、推导和论证,因而,在有些问题上,学生在理解和应用时,就会出现不少毛病。比如,在判断化学反应的方向和限度时,虽然同学们知 In inorganic chemistry teaching, the application of thermodynamics to discuss related issues has only begun in recent years in China. The introduction of thermodynamics, for us to discuss related issues, such as the direction and limits of chemical reactions, the thermodynamic stability of compounds, etc., undoubtedly brought great convenience, and therefore very popular. However, due to the teaching requirements and limitations of inorganic chemistry, it is not possible to introduce detailed introduction, derivation and argumentation of the introduced thermodynamic problems. Therefore, in some problems, students will have many problems when they understand and apply them. . For example, when judging the direction and limits of a chemical reaction, the students know that
