A kinetic study on Thermodynamic parameter of solvolysis reaction of methyl salicylate in water-DMF solvent system using different concentration of DMF (v/v) was made at four different temperature i.e. 20o C, 25o C, 30o C, 40o C. It was observed that with increasing concentration (mole %) of the organic co-solvent in the reaction media, the values of the reaction goes on descending while value goes on enhancing. Hence, it was inferred that the reaction was entropy control. The evaluated values of Iso-kinetic temperature are come to 202.62, which is less than 300, indicate weak interaction between solvent and solute present in the reaction media.
