Solution

The correct option is C $K_{C} = {[{N O}_{2}]}^{4} [O_{2}]$
Reactions containing pure solids and liquids results in heterogeneous reactions in which the concentrations of the solids and liquids are not considered when writing out the equilibrium constant expressions. Thus the $K_{c}$ of this equilibrium is : $K_{C} = {[{N O}_{2}]}^{4} [O_{2}]$
