Excess Gibbâ??s free energy function values at different temperatures in binary liquid mixture for the study of molecular interactions


Density, ultrasonic velocity and viscosity values have been measured experimentally in the binary mixture containing quinolone and m-xylene at different temperatures at different mole fractions. These experimentally measured data have been used to calculate the excess Gibb’s free energy function (G*E).The obtained results have been used to explain the molecular interactions.
