Perturbation Theories for
Simple Fluid Mixtures
This chapter analyzes a number of perturbation theories for mixtures of simple fluids
like those considered in Chapter 6. Apart from the quite straightforward extensions
to mixtures of some of the integral equation and integral equation theories introduced
in Chapter 4, which are cited in passing, the formulation for mixtures of several of
the free energy perturbation theories addressed in Chapter 6 is described. In addition,
this chapter describes a number of models, related to conformal solution theory,
specifically designed for mixtures. Particular attention is paid to theories for HS
mixtures, as
