Well, you need the chemical equation first.

Explanation:

Typically K_"eq" = "Concentrations of reactants"/"Concentration of products". Each term is appropriately modified depending on its multiplicity in the defining chemical equation.

Say for dinitrogen fixation:

N_2(g) +3H_2(g) rightleftharpoons 2NH_3(g)

K_"eq" = ([NH_3]^2)/([N_2][H_2]^3)
