Vedclass · Answer

(D) The acid-catalyzed hydrolysis of an ester is a reaction whose rate depends on the concentration of hydrogen ions $[H^+]$.For $0.1 \ N$ $HCl$,the concentration of $[H^+]$ is $0.1 \ M$ because $HCl$ is a monoprotic acid.For $0.1 \ N$ $H_2SO_4$,the normality is $0.1 \ N$. Since $H_2SO_4$ is a diprotic acid,its molarity is $0.05 \ M$,and the concentration of $[H^+]$ is $2 	imes 0.05 \ M = 0.1 \ M$.Since the concentration of $[H^+]$ is the same $(0.1 \ M)$ in both cases,the rate of reaction $(R)$ will be equal.Therefore,$R_{HCl} = R_{H_2SO_4}$.

The hydrolysis of an ester was carried out separately with $0.1 \ N$ $HCl$ and $0.1 \ N$ $H_2SO_4$. Then for the rate of reaction $(R)$ in the presence of acid,which of the following relations is true?
