Abstract
The Lennard-Jones attractive and repulsive contributions of intermolecular forces (as separated in the Weeks-Chandler-Andersen (WCA) theory) to the pr essure and chemical potential of coexisting vapour and liquid phases are ob tained by using an equation of state recently proposed by us. Some comments are given about the computer simulation results obtained by Plackov and Sa dus (1997, Fluid Phase Equilib., 134, 77) using the McQuarrie-Katz separati on of the intermolecular potential.
