$CH_3COOCH_3 + H_2O \xrightarrow{H^{+}} CH_3COOH + CH_3OH$

Vedclass · Answer

(A) In a chemical reaction,if one of the reactants is present in large excess,the reaction follows first-order kinetics even if the molecularity is higher. This is known as a pseudo unimolecular reaction.The acid-catalyzed hydrolysis of methyl acetate is a classic example:$CH_3COOCH_3 + H_2O \xrightarrow{H^{+}} CH_3COOH + CH_3OH$Here,water is present in large excess,so its concentration remains effectively constant during the reaction. The rate law is given by $Rate = k[CH_3COOCH_3]$. Thus,the reaction is of the first order,making it a pseudo unimolecular reaction.

Which of the following is an example of a pseudo unimolecular reaction?
