Abstract : The data for the H2-NO reaction have been reexamined in the light of new data on elementary reaction steps, with direct integration of the governing differential equations. The reaction HNO + NO = N2O + OH has been found to be an important, slow step. The initial rate, for stoichiometric mixtures and excess H2, is second order in NO and one-half order in H2 in agreement with some of the data. The reactions H2 + NO = HNO + H and H + NO + M = HNO + M are nearly equilibrated under most conditions. The over-all initial rate is proportional to the HNO + NO rate which has a rate constant of 6.14 (10 to the 12th power)e to the minus 34100/RT cc/mole sec. The rate at greater times is less than second order in NO (approx 1.75) and slightly greater than one-half order in H2, in qualitative agreement with the available data. (Author)
