If there is a reaction in which there is only gas in the reactants and they form solids do you then just put a one in the denominator of the kc equation.

### Re: What do you do if all products are pure substances?

Yes, you would just put 1 (but in the numerator since the products are in the numerator and the reactants are in the denominator)

### Re: What do you do if all products are pure substances?

Yes, you would only include the gases in the $K_{p}$, and the numerator would be 1 since the equilibrium constant for partial pressure is the concentrations of partial pressure of products over partial pressure of reactants:

$K_{p}=\frac{[P_{products}]}{[P_{reactants}] }$
