Question

The rate constant for the hydrolysis of ethyl acetate in the presence of 0.1 NHCl was found to be 6.20 x 10^-5s^-1 and for the hydrolysis of ethyl acetate in the presence of 0.1 N  H₂ SO₄ its was 5.40 x 10^-5s^-1 From these two observations one may conclude that 

(A) H₂ SO₄ and HCl are both of the same strength

(B) H₂ SO₄ is weaker than HCl

(C) H₂ SO₄ is stronger than HCl

(D) the data is insufficient to compare the strengths of H₂ SO₄ and HCl

Answer 1

Correct Option (B) H₂ SO₄ is weaker than HCl

Explanation: 

We know that [H^-] acts as catalyst in hydrolysis of ethyl acetate
