The ultrasonic velocity (U), density (ρ) and viscosity (η) have been measured for the binary mixture of 1-Bromopropane with Chlorobenzene at 303.15, 308.15, 313.15 and 318.15 K at frequency 2 MHz. From the experimental data acoustical parameters such as adiabatic compressibility (βad), intermolecular free length (Lf), acoustic impedance (Z), molar volume (Vm), free volume (Vf), available volume (Va), relaxation time (τ), internal pressure (πi) and Gibbs’s free energy (ΔG*) have been computed. These results are interpreted in terms of molecular interaction between the components of the mixtures.
