Abstract: Excess thermodynamic properties i.e. excess volume, excess molar enthalpy, excess molar entropy, excess free energy and excess heat capacity have been evaluated using Prigogine-Flory-Patterson (PFP) and Bertrand-Acree-Bruchfield (BAB) theory for three ternary and its contributory binary liquid systems namely (1) tolune- cyclohexane- carbon tetrachloride and its contributory binaries (toluene+ cyclohexane), (cyclohexane + carbon tetrachloride), (carbon tetrachloride + toluene); (2) benzene – cyclohexane- toluene and its contributory binaries, (benzene + cyclohexane), (cyclohexane + toluene), (toluene + benzene); (3) carbon tetrachloride- cyclohexane – benzene and its contributory binaries, (carbon tetrachloride + cyclohexane), (cyclohexane + benzene) and (benzene + carbon tetrachloride) at 298.15 K over a wide range of compositions. . The results so obtained from these two theories are very much comparable and are in good agreement.
