ABSTRACT:
The rate of solvolysis of ethyl benzoate was estimated volumetrically over the temperature range of 200c to 400c.in water-methanol mixture at different composition. The depletion and enhancement in value of iso-composition activation energy and iso- dielectric activation shows solvation in transition state and de-solvation in initial state respectively. The effect of solvent on reaction rate was tested in term of activation parameter. Simultaneous decrease in values of ?H* and ?S* with increase in value of ?G* with solvent composition show that the reaction is Enthalpy domination and Entropy controlled. There is weak interaction between solvent and solute because the values of iso-kinetic temperature is less than 300 K/Mole2
