For the following equilibrium, at Both the forward and reverse reactions in the equilibrium are elementary bimolecular reactions. What is , for the reverse reaction?

Answer:

Kp and Kc are equilibrium constants for reversible reactions. The equilibrium constant Kp is stated in terms of atmospheric pressure, whereas Kc is expressed in terms of concentrations expressed in molarity. Understanding Kp and Kc leads to the Kp Kc connection.

For the reverse reaction, relation between equilibrium constants are,

Substuting the given values we have,

Thus, value of Kc
