Question

Saponification of ethyl acetate (CH3COOC2H5) by NaOH (Saponification of ethyl acetate by NaOH is second order Rxn) is studied by titration of the reaction mixture initially having 1:1 molar ratio of the reactants. If 10 mL of 1 N HCl is required by 5 mL of the solution at the start and 8 mL of 1 N HCl is required by another 5 mL after 10 minutes, then rate constant is :

Options

A.k =
B.k =
C.k =
D.k =

Solution

Saponification of ethyl acetate by NaOH is second order Rxn
Then    k =
            k =
