The classical configurational free-energy of a system of molecules with steep intermolecular potentials is obtained from that of a system of hard spheres by an expansion in powers of n -1, where n is a measure of the steepness of the potential. It is shown that the free energy can be obtained explicitly and exactly to the order of n -1. Higher terms have non-thermodynamic coefficients. The first-order term yields an excellent equation of state for gases at high temperatures and densities. It… CONTINUE READING
