版权所有：华东理工大学物理化学教研室 2 Part 1: Equilibrium Bilingual Program 5. The Second Law:the machinery
版权所有：华东理工大学物理化学教研室 3 In 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 T and 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. The 'chemical potential', the quantity on which almost all the most important applications of thermodynamics to chemistry are based. 5. The Second Law: the machinery
