• [A](s) = [B](l) = 1

The equilibrium constant expression would be as follows:

`K_c = ([G]^g [H]^h)/(1) * 1 = [G]^g [H]^h`

*In this case, since solids and liquids do not affect the equilibrium constant expression, the expression is independent from the concentration of the reactants. Thus, we must leave A and B out of the final expression. When the product of the reaction is a solvent, the numerator equals one, which is illustrated in the following reaction:

`H^(+) (aq)+OH^(-) (aq) -> H_2O(l)`

The equilibrium constant expression would be:

`K_c= 1[H^(+)][OH^(-)]`
