determination of activation energy for acid catalyzed hydrolysis of ethyl acetate
5 ml of ester is pipetted out into the conical flask and the mixture is immediately withdrawn into another dry conical flask.
A stop watch is started simultaneously.
The reaction is then arrested by the addition of ice cubes and the mixture is titrated against 0.
2) N NaOH using phenolphthalein as indicator.
What is the kinetic study of acid-catalyzed hydrolysis of ethyl acetate experiment?
The kinetic study of hydrolysis of ethyl acetate is catalysed by an acid, and is followed by titrating a fixed volume of a reaction mixture with a standard alkali solution, at different intervals of time.
The ester hydrolysis is acid catalysed.
What is the activation energy for acid-catalyzed hydrolysis of ethyl acetate?
The acidic formation of ethyl acetate is an exothermic process with an estimated 16–40 kJ. mol-1 activation energy.
The enthalpy of ethyl acetate formation in the liquid form is approximately -480 kJ. mol-1.3 jui. 2023
