NEET 2024 Chemistry question on Equilibrium

Consider the following reaction in a sealed vessel at equilibrium with concentrations of $\mathrm{N_2} = 3.0 \times 10^{-3}$ M, $\mathrm{O_2} = 4.2 \times 10^{-3}$ M and NO $= 2.8 \times 10^{-3}$ M.

$2\mathrm{NO_{(g)}} \rightleftharpoons \mathrm{N_{2(g)}} + \mathrm{O_{2(g)}}$

If 0.1 mol $\mathrm{L^{-1}}$ of $\mathrm{NO_{(g)}}$ is taken in a closed vessel, what will be degree of dissociation ($\alpha$) of $\mathrm{NO_{(g)}}$ at equilibrium?
