Nitric oxide (NO) is a major pollutant formed in high-temperature combustion processes, but typically in less than equilibrium amounts. Equilibrium values thus can be considered to be upper limits. For the equilibrium reaction N₂ + O₂ ⇔ 2 NO determine the equilibrium partial pressures and the mole fractions (in parts per million) of the nitric oxide at combustion-like conditions of 2200 K and 10 atm. The initial mole fractions of O₂ and N₂ prior to the formation of any NO are 0.21 and 0.79, respectively, the approximate values for air.
