The Ultrasonic velocity, density, and viscosity have been measured for ternary mixture of N-N dimethyl formamide (DMF), Cyclohexane and Chloro-benzene at different temperatures for a constant frequency (6 MHz). These experimental data have been used to estimate the thermodynamic parameters such as adiabatic compressibility (β), free length (Lf), internal pressure (??Ÿi), relaxation time (τ), acoustic impedance (Z), and Gibb’s free energy (ΔG) for the solution. The excess values of the parameters are also evaluated and discussed.
