Abstract: The intermolecular forces of liquids in a mixture show a considerable effect on the physical and chemical properties. A detailed study of the thermodynamic, transport and dielectric properties of fluids and fluid mixtures is important not only for the solution problems but also for the development of understanding of molecular motions and interactions in such systems. There is a continue need for reliable thermodynamic data of binary systems for chemical industries as the data is essential in the design of process involving chemical separation heat transfer, mass transfer and fluid flow. The present study deals with the variations of ultrasonic velocity, density, viscosity, various acoustic and thermodynamic parameters such as adiabatic compressibility, intermolecular free length, molar volume, acoustic impedance, free volume, internal pressure, enthalpy and also excess thermodynamic properties for Ethanol with ethyl acetate as function of concentration and temperature. All the excess parameters are fitted into the Redlich-Kister equation. And also to compare the ultrasonic sound velocity in Ethyl Acetate with Ethanol mixture from various theoretical relations of Nomoto and Van Dael Vangeel. These properties can be effectively utilized as a qualitative study to predict the extent of molecular interactions between the components.
