Activation Parameters and Solvent Effect : A Kinetic Reaction OF Ethyl Caprylate in Water-Acetone Media.

Anil Kumar Singh

The kinetic result of hydrolysis of Ethyl Caprlyate was investigated at different composition of aqueous organic solvent with Acetone (30-70% v/v) over the temperature range of 20 to 400c. The calculated result follows second- order kinetics and observed that the rate decreases with increasing proportion of acetone. This behavior is attributed the electrostatic nature that various solvent-solute interactions occurs in the reaction media. Linear plots of logk with different water concentration show that the equilibrium shifted from dense form to bulky form. Iso-kinetic temperature has been determined with the help of slopes of versus. Thermodynamic parameter was calculated with the help of Wynne-Jones and Eyring equation.
