Consider the reaction:$$\mathrm{N_2(g) + 3H_2(g) <=> 2NH_3(g)}$$At a certain temperature, the equilibrium constant $K_c$ for this reaction is $5.6 \times 10^{-5}$. If a reaction vessel initially contains only $\mathrm{0.10\,mol}$ of $\mathrm{N_2}$ and $\mathrm{0.20\,mol}$ of $\mathrm{H_2}$, what will be the equilibrium concentrations of $\mathrm{N_2}$, $\mathrm{H_2}$, and $\mathrm{NH_3}$ once the reaction reaches equilibrium?
