Chemistry - Chemical Equilibrium Question with Solution | TestHub

For the reaction 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 ${\mathrm{K}}_{\mathrm{c}}$ for the reaction is
