When ethyl acetate was hydrolyzed in the presence of `0.1 M HCl`, the constant was found to be `5.40 xx 10^(-5) s^(-1)`. But when `0.1 M H_(2)SO_(4)` was used for hydrolyiss, the rate constant found to be `6.20 xx 10^(-5) s^(-1)`. form these we can say that

A

`H_(2)SO_(4)` is stronger than `HCl`

B

`H_(2)SO_(4)` and `HCl` are both of the same stength of `HCl`

C

`H_(2)SO_(4)` is weaker than `HCl`.

D

The data is insufficient to compare the strength of `HCl` and `H_(2)SO_(4)`.

Text Solution

Verified by Experts

The correct Answer is:
A
Since `k_(H_(2)SO_(4)) gt k_(HCl)`, hence `H_(2)SO_(4)` is stronger acid than `HCl`.
