What is the saponification reaction of ethyl acetate?
The hydrolysis of ethyl acetate with sodium hydroxide to produce ethanol and sodium acetate is known as a saponification reaction.
The end products of saponification reaction (i. e., sodium acetate and ethanol) are used in various fields – for instance, the petroleum, textile, cosmetics, and paint industries.
For the saponification of ethyl acetate, the entropy of activation was determined to be ΔS‡ = −74.
7) J mol⁻¹ K⁻¹ and enthalpy of activation ΔH‡ = 46.3 kJ mol⁻¹.

What is the activation energy of hydrolysis of ethyl acetate?

The initial rate constant at 25°C was measured as 0.1120 1./mol./sec. and the activation energy was 11.56 kcal./mol., values agreed well with those of previous studies.

What is the activation energy of the saponification reaction?

The determined activation energy of the Saponification reaction between olein and sodium hydroxide is 2.53 J mol−1.
However, there are a few interesting inferences that can be drawn from the results obtained.

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.
