Ultrasonic Studies on the Thermodynamic and Excess Thermodynamic Properties of Bromobenzene Substituted with Ethyl Methyl Ketone at 308.15 K

The ultrasonic velocity, viscosity and density of the bromobenzene substituted with ethyl methyl ketone system have been measured experimentally at 308.15 K over the frequency 2 MHz. From these three values, we have calculated thermodynamic and excess thermodynamic parameters such as molar volume, excess molar volume, adiabatic compressibility, deviation in adiabatic compressibility, intermolecular free length, excess intermolecular free length, deviation in viscosity, acoustic impedance, excess acoustic impedance,excess velocity, Rao's constant and Wada's constant of binary mixtures to interpret the nature of the interactions taking place in the binary liquid solutions. We have also calculated the ultrasonic velocity using two different models theoretically (Nomoto's relation and Van Dael ideal mixing relation). The negative values of the excess intermolecular free length and the non-linear changes of the ultrasonic velocity of the system obviously specified the prevalence of interactions among molecules of binary liquids.
