Question

When ethyl acetate was hydrolyzed in the presence of 0.1 m HCl, the constant was found to be 5.40 × 10-5 s-1. But when 0.1 M H2SO4 was used for hydrolysis, the rate constant was found to be 6.20 × 10-5 s-1. From these we can say that

Options

A. H2SO4 is stronger than HCl.
B.H2SO4 and HCl are both of the same strength.
C.H2SO4 is weaker than HCl.
D.The data is insufficient to compare the strength of HCl and H2SO4.

Solution

Since kH2SO4 >  kHCl, hence H2SO4 is stronger acid than HCl.
