#### Answer

$K_{c} = \frac{[N_{2}O][NO_{2}]}{[NO]^3}$

#### Work Step by Step

The expression for Kc is the concentration of products raised to their respective stoichiometric coefficients divided by the concentration of the reactants raised to their stoichiometric coefficients. For the reaction: 3 NO N2O + NO2 we would have $K_{c} = \frac{[N_{2}O][NO_{2}]}{[NO]^3}$
