Acoustic thermo analytical study with coeffecients of Redlich Kister polynomial in material combinations at 303.15K temperature to 318.15K temperature.

Acoustical thermodynamic work is to estimate excess thermodynamic properties with coefficients of Redlich Kister polynomial equation in the studied functional liquid mixture combination (O-anisidine combined with Amyl acetate). Evaluated excess acoustical excess values such as Gibb's parameter (GE), total heat function or enthalpy (NE) & internal pressure (PE) are measured with experimental studied information. Further effects have additionally been beneficial to attain Redlich-Kister parameters from equation of polynomial and additionally to acquire their deviations and are analyzed to understand the molecular interactions among thing molecules at recognised temperatures variety from temperature 303.15K to 318.15K.
