For the reaction in equilibrium,
\[
\mathrm{N}_{2} \mathrm{O}_{4}(\mathrm{~g}) \rightleftharpoons 2 \mathrm{NO}_{2}(\mathrm{~g})
\]
the concentrations, of \( \mathrm{N}_{2} \mathrm{O}_{4} \) and \( \mathrm{NO}_{2} \) at equilibrium are \( 4.8 \times 10^{-2} \) and \( 1.2 \times 10^{-2} \mathrm{~mol} \mathrm{~L}^{-1} \) respectively. The value of \( K_{c} \) for this reaction is :
(A) \( 3 \times 10^{-3} \mathrm{~mol} \mathrm{~L}^{-1} \)
(B) \( 3 \times 10^{3} \mathrm{~mol} \mathrm{~L}^{-1} \)
(C) \( 3.3 \times 10^{2} \mathrm{~mol} \mathrm{~L}^{-1} \)
(D) \( 3 \times 10^{-1} \mathrm{~mol} \mathrm{~L}^{-1} \)
