The equilibrium constant for the reactio...

The equilibrium constant for the reaction `2X+Y leftrightarrow X_2Y` is `10 L^2 mol^-2`. The rate constant for the backward reaction `28s^-1`. What is the rate constant of the forward reaction.

Text Solution

Verified by Experts

Equilibrium constant `K_2=10= K_f/K_b=K_f/28`
Forward rate constant, `k_f=280 L^2 mol^-2 s^-1`
