Question

The hydrolysis of ethyl acetate
CH,COOC,H,+H.0_">CH,COOH + C,H,OH​

Answer 1

Answer:

A reaction which is not the first-order reaction naturally but made the first order by increasing or decreasing the concentration of one or the other reactant is known as Pseudo first-order reaction.

Hydrolysis of ethyl acetate in presence of an excess of water:
