Abstract: Ultrasonic velocity, density and viscosity have been measured experimentally and free volume as well as internal pressure and enthalpy were calculated for the binary mixtures of o-chlorophenol with ethyl benzoate, anisic aldehyde and acetonitrile at 303.15, 308.15, 313.15 and 318.15 K over the entire range of composition. Excess values of free volume, internal pressure, enthalpy and Gibb’s free energy of activation have been calculated for these systems. The results were discussed in the light of existing theories of molecular interactions involved and chemical constitution of the liquid components.
