The consumption of nitric oxide in the shock‐heated nitric oxide, hydrogen, and argon system had been studied and modeled as the chain‐branching process containing the reaction H + NO ⇀ N + OH ( k 3 ) as a slow‐branching step. Through the computer simulation method the authors clarified the role of the initiation reaction H 2 + NO ⇀ HNO + H ( k 1 ) in the system and obtained the rate constants of k 1 and k 3 as k 1 = 10 13.5±0.15 exp (−55.2 kcal/ RT ) and k 3 = 10 13.7±0.15 exp (−48.7 kcal/ RT ) (cm 3 /mole·sec), respectively. k 1 was one order larger than the value obtained in the flame experiment by Halstead and Jenkins.
