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?

0.24

Explanation:

We are given that

Rate constant for A=

Rate constant for  B,k'=0.0750/s

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

Equilibrium constant, for k=

Using the formula

Hence, the value of the equilibrium constant for the reaction

at this temperature=0.24

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
