摘要:

热力学方程是包含热力学基本方程、热力学状态方程以及吉布斯-亥姆霍兹方程在内的广泛的一组方程。文中对目前物理化学教材中很少提及的其他热力学状态方程进行了系统的总结和推导,同时强调理论的系统性和完整性在教学中的重要性,并在此基础上导出了物理化学教材中很少见到的吉布斯-亥姆霍兹第一方程及其在表面化学中的应用。在物理化学教学中需要特别强调特征变量的重要性,以及特征变量和化学反应条件之间的内在关系,并注意与交叉学科物理专业的热力学和统计物理学的衔接。

关键词: 麦氏关系, 特征变量, 热力学基本方程, 热力学状态方程, 吉布斯-亥姆霍兹方程

Abstract:

The thermodynamic equation includes basic thermodynamic equations, the thermodynamic state equations, and Gibbs-Helmholtz equations. In this paper, we derived the other thermodynamic state equations which are rarely mentioned in physical chemistry teaching materials. At the same time, we emphasized the systematic characteristics and the completeness of the thermodynamic theory. Furthermore, the application of surface chemistry was concluded from the first Gibbs-Helmholtz equations. Finally, we emphasized the relations between the characteristic variables and the reaction conditions.

Key words: Maxwell′s relations, Characteristic variable, Basic thermodynamic equation, Thermodynamic state equation, Gibbs-Helmholtz equation
