Question

What happens to the equilibrium constants if twoo reactions are subtracted?

Answer 1

The equilibrium expression written for a reaction written in the reverse direction is the reciprocal of the one for the forward reaction. K' is the constant for the reverse reaction and K is that of the forward reaction. ... The desired reaction is the reverse of the reaction for which the Kc is known.

Answer 2

Explanation:

If two or more reactions are added to give another, the equilibrium constant for the reaction is the product of the equilibrium constants of the equations added. ... represent the equilibrium constants for reactions being added together, and K' represents the equilibrium constant for the desired reaction.
