Question

The rate constant for forward reaction and backward reaction of hydrolysis of ester are \( 1.1 \times 10^{-2} \) and \( 1.5 \times 10^{-3} \) per minute respectively. Equilibrium constant for the reaction is?

• A. 33.7
• B. 7.3
• C. 53
• D. 33

Hint:

The equilibrium constant can be calculated by dividing the rate constant of the forward reaction by the rate constant of the reverse reaction.

Answer 1

The Correct Option is B

The equilibrium constant \( K \) for a reversible reaction is the ratio of the rate constants for the forward and reverse reactions: \[ K = \frac{k_f}{k_r} \] where \( k_f \) is the rate constant for the forward reaction and \( k_r \) is the rate constant for the backward reaction.
