Molecular Thermodynamics of Fluid-Phase Equilibria

Chapter 4 Intermolecular Forces, Corresponding States and Osmotic Systems

Thermodynamic properties of any pure substance are determined by intermolecular forces that operate between the molecules of that substance. Similarly, thermodynamic properties of a mixture depend on intermolecular forces that operate between the molecules of the mixture. The case of a mixture, however, is necessarily more complicated because consideration must be given not only to interaction between molecules belonging to the same component, but also to interaction between dissimilar molecules. To interpret and correlate thermodynamic properties of solutions, it is therefore necessary to have some understanding of the nature of intermolecular forces. The purpose of ...
