Scaled-Particle Methods for a Hard Convex-Body Fluid

Abstract

Using the methods of Reiss et al. in the evaluation of the radial distribution function for a hard‐sphere fluid, an equation of state can be derived for a fluid of hard bodies of any convex geometry. The equation of state is derived for CCl₄, and the compressibility factor plotted versus the reduced volume. Expressions for the expansivity, isothermal compressibility, and enthalpy of vaporization are derived. Preliminary calculations show numerical improvement for β and ΔH_vap. Reiss' expansivity has an incorrect temperature coefficient; this dependence is correct in the convex‐body representation.
