Solvolysis Rate and Activation Parameter of Ethyl Acetate in mixed Dipolar Organic Solvent Systems – A Solvent Effect
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 10
Abstract
The rate of alkaline hydrolysis of ethyl acetate were measured over the temperature range of 20o C to 40 o C in watermethanol and water-ethanol mixture at different composition 30 to 70% (v/v). The influence of solvent variation on reaction rate was examined in term of changes in the Activation parameter. Depletion of H* and S* value with simultaneous increase in G* of the reaction in both media, reveals that the reaction is Enthalpy domination and Entropy controlled. The Values of Iso-kinetic which is less than 300, clearly indicates that there is no appreciable interaction between solvent and solute present in the reaction media, i.e. reaction is not ion-dipole but ion-molecule type.
