Analytical study of thermo acoustical excess parameters and Redlich-Kister coefficients in functional materials at known four temperatures range from 303.15 K to 318.15 K

The Analysis of the present work is related to study involved in investigation of excess thermal acoustic parameters and their Redlich Kister Coefficients at different temperatures and all these are analyzed in liquid mixtures containing three functional material combinations namely (Aniline mixed with Toluene), (Aniline mixed with o-Xylene) and (Aniline mixed with Mesitylene). The obtained excess values of acoustical parameters namely Gibb's free energy (G*E) , enthalpy (HE) and internal pressure (pE) have been computed from measured experimental data . The results have also been helpful to obtain RedlichKister coefficients from polynomial equation and also to obtain their deviations. Excess thermoacoustical parameters are discussed along with Redlich-Kister coefficients generally for the study of interactions among the molecules of liquid species and they are analyzed at known temperatures range from 303.15 K to 318.15 K with variation of 5 K temperature interval for each study.
