Abstract: The vapor pressures of benzcne-cyclonexane (313.25K), benzene-n-heptane (308.1119K) and cyclohexane-n-heptane (298.15K) were measured with a tensi-meler. By correlating the vapor pressures with their respective solution compositions, excess Gibbs free energies were calculated by Wilson and Redlich-Kister cquations, in good agreement with published data.
