化学平衡必然性的简要论证和正确图示

化学平衡是化学反应的重要规律 ,化学平衡必然性的论证又是物理化学中必列内容 .但现在常用的物理化学教材对此缺乏严谨而简明的推证 .本文根据函数取极值的必要条件 ,直接由吉布斯自由能G对反应进度 ζ的偏微商 ( G ζ) T .P的函数组成及取值 ,应用数学分析基本原理进行了简要的论证 .本论证直观、便捷 ,并对化学反应的平衡必然性的图示和教具制作也附带作了讨论

A brief demonstrating and instructing through diagrams for necessity of chemical equilibrium

Chemical equilibrium is an important law for chemical reaction,the demonstrating for its necessity is indispensable conten in physicochemistry textbooks.Unfortunately,there is no a rigorous simple and clear deduction for it in the commonly used physicochemistry textbooks.In the present paper,the verification of the nexessity was simply deduced based on the necessary condition for extreme value of a function.Additionally discussion in this paper is illustration and fabrication of demonstration model for teaching.
