For elementary gaseous phase reaction $2\mathrm{NO}+{\mathrm{O}}_2\rightleftharpoons 2{\mathrm{NO}}_2$ at $27^{\circ }\mathrm{C}$ Rate of the forward reaction is given by rate $=2\times 10^3[\mathrm{NO}{]}^2\left[{\mathrm{O}}_2\right]$ and Rate of reverse reaction at $27^{\circ }\mathrm{C}$ is given by rate $=20{\left[{\mathrm{NO}}_2\right]}^2$ Hence equilibrium constant for reaction

${\mathrm{NO}}_2\rightleftharpoons {\mathrm{NO}}_{}+\frac{1}{2}{\mathrm{O}}_2$ at 27ºC
