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]

Options

A. `K_(HCI=K_(H_(2)SO_(4)`
B. `K_(HCIgtK_(H_(2)SO_(4)`
C. `K_(HCI)ltK_(h_(2)SO_(4)`
D. `K_(H_(2)SO_(4))=2K_(HCI)`

Answer

B

Explanation

`[H_(2)SO_(4)]=0.1 M =0.1 xx2=0.2 N [HCI]=0.1 N`
In case of HCI `r_(2)=k[H^(+)]["Easter"] k_(HCI)=(r_(2))/("In xx ["Ester"])` Hence `k_(HCI) gt K_(H_(2)SO_(4)`
