Problem

The reaction N2(g)+O2(g)⇌2NO(g)\text{N}_2(\text{g}) + \text{O}_2(\text{g}) \rightleftharpoons 2\text{NO}(\text{g}) is carried out in a closed container with initial concentrations of both reactants of 1.6 mol dm−31.6 \text{ mol dm}^{-3}. KK for the reaction is 1.7×10−31.7 \times 10^{-3}. Calculate the concentration of NO(g)\text{NO}(\text{g}) at equilibrium.
