The hydrolysis of an ester was carried out with `0.1 M H_(2)SO_(4)` and 0.1 M HC1 separately. Which of the following expressions between the rate constants is expected? The rate expression being rate =k `[H^(+)]`[ester]

A

`k_(HCl) = k_(H_(2)SO_(4))`

B

`k_(HCl) gt k_(H_(2)SO_(4))`

C

`k_(HCl) lt k_(H_(2)SO_(4))`

D

`k_(H_(2)SO_(4)) = 2k_(HCl)`

Text Solution

`[H_(2)SO_(4)] = 0.1 M = 0.1 xx 2 = 0.2 N, " "[HCl] = 0.1 N`
In case of `H_(2)SO_(4) " "r_(1) = k[H^(o+)]["Ester"] " "k_(H_(2)SO_(4)) = (r_(1))/(2N xx ["Ester"])`
In case of HCl , `r_(2) = k[H^(o+)]["Ester"] " "k_(HCl) = (r_(2))/(1N xx ["Ester"])` Hence `k_(HCl) gt k_(H_(2)SO_(4))`
