Vapor‐liquid equilibrium compositions have been measured for the argon‐methane system at 115.2°, 123.4° and 137.1°K, by means of a forced‐recirculation apparatus. A modified Redlich‐Kwong equation of state with the incorporation of a binary interaction constant has been successfully employed to represent the data. Liquid activity coefficients have been evaluated and correlated.
