Activation Parameter and Solvent Effect on Solvolysis of Ethyl Benzoate in Aquo-Organic Solvent System.
Journal Title: To Chemistry Journal - Year 2019, Vol 2, Issue 0
Abstract
The rate of hydrolysis of hydrolysis of ethyl benzoate were measured volumetric over the temperature range of 200c to 400c.in water-methanol mixture at different composition. The different solvation in initial and transition state is due to decrease in rate with varying the composition of mixture. The influence of solvent on reaction rate was examined in term of activation parameter. The increase in values of DG* and simultaneous depletion in values of DH* and DS* with solvent composition reveals that the reaction is Enthalpy domination and Entropy controlled. The value of iso-kinetic temperature is less than 300 shows the weak interaction between solvent and solute.
