n this chapter First: to find relations between properties that might not be thought to be related to derive expressions for the variation of the g with Tand p Second: to introduce the chemical potential, a property that will be at the center of discussions in the remaining chapters of this part of the text; to derive expression of fugacity

一、吸附特点 固体在溶液中除了吸附溶质外还会对溶剂进行吸附，吸附规律比较复杂。 固体自溶液中的吸附要考虑三种作用力： a.在界面层上固体与溶质之间的作用力； b.固体与溶剂之间的作用力 c.溶液中溶质与溶剂之间的作用力。 溶液中的吸附是溶质与溶剂分子争夺固体表面的净结果
