Formation of NO from N₂/O₂ Mixtures in a Flow Reactor: Toward an Accurate Prediction of Thermal NO

We have conducted flow reactor experiments for NO formation from N 2 /O 2 mixtures at high temperatures and atmospheric pressure, controlling accurately temperature and reaction time. Under these conditions, atomic oxygen equilibrates rapidly with O 2 . The experimental results were interpreted by a detailed chemical model to determine the rate constant for the reaction N 2 + O ⇌ NO + N (R1). We obtain k 1 = 1.4 × 10 14 exp(−38,300/ T ) cm 3 mol...
