Activation energy for the acid catalysed hydrolysis of sucrose is 6.22 KJ mol−, while the activation energy is only 2.15 KJ mol− when hydrolysis is catalysed by the enzyme sucrase.
What is the activation energy of 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
What is the activation energy of saponification ethyl acetate?
In their study, they used 0.
8) M ethyl acetate and 1.
0) M NaOH and conducted the experiments at five different temperatures ranging form 30 to 70°C.
They obtained the value of activation energy, 46.5 kJ mole−1, which was about 10% higher than the present value.
