K =( k f / k r ) ∴ k r =( k f / K )=(30.5/10) =3.05

Q. The equilibrium constant of the reaction $A + B ⇌ C + D$ is $10$ . If rate constant of forward reaction is $30.5$ , then the rate constant of backward reaction is_____.

$K = \frac{k _{f}}{k _{r}}$
$∴ k_{r} = \frac{k _{f}}{K} = \frac{30.5}{10}$
$= 3.05$
