Hydrolysis of ethyl acetate into acetic acid and ethanol in the presence of mineral acid is:
Correct answer: B. Pseudo 1st order reaction
- A. Fractional order reaction
- B. Pseudo 1st order reaction
- C. 1st order reaction
- D. 2nd order reaction
Explanation
Although the reaction is second order overall (first order in ethyl acetate and first order in H₂O), water is in large excess, so its concentration is essentially constant.This makes the reaction appear to follow first-order kinetics, called a pseudo first-order reaction.

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
