Hydrolysis of methyl acetate in dilute solution

Vedclass · Answer

(B) The correct answer is $(B)$.The hydrolysis of methyl acetate in a dilute aqueous solution is represented by the equation: $CH_3COOCH_3 + H_2O \xrightarrow{H^{+}} CH_3COOH + CH_3OH$.In this reaction,water is present in large excess,so its concentration remains practically constant during the reaction.Therefore,the rate of the reaction depends only on the concentration of methyl acetate,making it a pseudo-$unimolecular$ reaction.
