Abstract
The present research work is related to the analysis involved in the study of excess acoustical parameters and their Redlich-Kister Coefficients at different temperatures range from 303.15 K to 318.15 K with variation of 5 K temperature interval for each study and all these are explained in liquid mixtures containing functional materials namely (Benzene mixed with 1-Propanol). The obtained excess values of acoustical parameters namely Gibb's free energy (G*E), enthalpy (HE) and internal pressure (nE) have been computed from measured experimental data. The results have also been helpful to obtain Redlich-Kister coefficients from polynomial equation and also to obtain their deviations. Excess thermo-acoustical parameters are discussed along with Redlich-Kister coefficients generally for the study of interactions among the molecules of liquid species.
