Answer
$K_{c}=\frac{[C]^{c}[D]^{d}}{[A]^{a}[B]^{b}}$
Work Step by Step
Equilibrium constant$(K_{c})$ is expressed by the ratio of the product of concentrations of the reaction products raising their stoichiometric coefficient in the balanced chemical equation to the power(taken as the numerator) and the product of concentrations of the reactants raising their stoichiometric coefficients to their power(taken as the denominator).
