偏摩尔量加和公式可能的两处新应用

Two New Applications of the Additivity Equation of Partial Molar Quantity

本文探讨了偏摩尔量加和公式的两处新的应用。其中之一应用于摩尔反应吉布斯自由能与化学势关系式的推解,另一应用于离子活度关系式的推解。在这两个关系式的推解过程中若采用偏摩尔量的加和公式,不仅可以使两个关系式的物理概念更加明晰,推导更加合理化,也可以使这两个关系式的适用环境更易被人接受和理解。

Two new applications of the additivity equation of partial molar quantity are discussed.One is applied in the deduction of the relationship about reaction Gibbs energy and chemical potentials of substances involved.Another is applied in the deduction of the relationship about molecular activity and relative ionic activities in strong electrolyte solution.These two new applications can make former two relationships clear,reasonable and easy to be understood.
