Question

At a given temperature, the elementary reaction A − ⇀ ↽ − B , in the forward direction, is first order in A with a rate constant of 0.0180 s − 1 . The reverse reaction is first order in B and the rate constant is 0.0750 s − 1 . What is the value of the equilibrium constant for the reaction A − ⇀ ↽ − B at this temperature?

Answer 1

Answer:

0.24

Explanation:

We are given that

Rate constant for A=$k=0.0180/s$

Rate constant for  B,k'=0.0750/s

We have to find the value of equilibrium constant for the reaction

$A\rightleftharpoons B$

Equilibrium constant, for k=$\frac{k}{k'}$

Using the formula

$k=\frac{0.0180}{0.0750}=0.24$

Hence, the value of the equilibrium constant for the reaction

$A\rightleftharpoons B$ at this temperature=0.24
