Nitric oxide, an important pollutant in air, is formed from the elements nitrogen and oxygen at high temperatures, such as those obtained when gasoline burns in an automobile engine. At 2000°C, K for the reaction N2(g) + O2(g) ⇆  2NO(g) is 0.010. If 0.40 moles of N2, 0.10 moles of O2, and 0.080 moles of NO are placed in a 1.0-liter container, what will be the concentration of O2 at equilibrium?
