A comparative study of excess Gibb?¢????s free energy function values in three binary liquid mixtures containing quinoline and o, m, p-xylenes at different temperatures T(=303.15, 308.15, 313.15 and 318.15)K


Viscosity, density and ultrasonic velocity values have been measured experimentally in three binary liquid mixtures containing (quinoline+o-xylene),(quinoline+m-xylene) & (quinoline+p-xylene) at different temperatures at different mole fractions. These experimentally measured values have been used to obtain the excess Gibb’s free energy function (G*E) in all the three binary liquid mixtures at different temperatures. The obtained results have been used to explain the molecular interactions.
