The gases NO and O2 are mixed in a container of fixed volume kept at 1000 K. Their initial concentrations are 0.0200 mol/L and 0.0300 mol/L, respectively. When the reaction 2NO(g) O2(g) ? 2NO2(g)has come to equilibrium, the concentration of NO2 is 2.2 x 10-3 mol/L. Calculate the molar concentration of O2 at equilibrium.
