(A) The equilibrium constant $K_c$ for the reaction $N_2O_{4(g)} ightleftharpoons 2NO_{2(g)}$ is given by the expression: $K_c = \frac{[NO_2]^2}{[N_2O_4]}$ Substituting the given equilibrium concentrations: $[NO_2] = 1.2 	imes 10^{-2} \ mol/L$ $[N_2O_4] = 4.8 	imes 10^{-2} \ mol/L$ $K_c = \frac{(1.2 	imes 10^{-2})^2}{4.8 	imes 10^{-2}}$ $K_c = \frac{1.44 	imes 10^{-4}}{4.8 	imes 10^{-2}}$ $K_c = 0.3 	imes 10^{-2} = 3 	imes 10^{-3} \ mol/L$ Thus,the correct option is $A$.

For the reaction in equilibrium $N_2O_{4(g)} \rightleftharpoons 2NO_{2(g)}$,the equilibrium concentrations of $N_2O_4$ and $NO_2$ are $4.8 \times 10^{-2} \ mol/L$ and $1.2 \times 10^{-2} \ mol/L$,then $K_C$ is
