The rate of solvolysis of ethyl benzoate was estimated volumetrically over the temperature range of 20°c to 40°c.in water-methanol mixture at different composition. The depletion and enhancement in value of isocomposition 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 δH* and δS* with increase in value of δG* 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
