Abstract

The reaction of dilute H2/O2/N2 and H 2/O2/Ar mixtures perturbed with small quantities of NO has been studied in a variable-pressure flow reactor between 800 and 900 K. At high pressures (10-14 atm), the consumption of H2 and the conversion of NO to NO2 were highly sensitive to the pressure-dependent reaction (Equation presented) Rate coefficient data for the low-pressure limit (Equation presented) were inferred by comparison of the experimental data with a reaction mechanism that uses the high-pressure limit k2,∞ = 4.52 × 1013 (T/300)0.6 with Fc N2 = 0.5 and FcAr = 0.45. The data obtained with M = Ar are consistent with previous shock-tube data at comparable temperatures and are in good agreement with recent recommendations for k 2,0Ar. However, the data obtained for M = N2 are 40% lower than recent recommendations and are combined with previously published data to yield (Equation presented) over the temperature range 300-1600 K. The rate coefficient data obtained in this study are insensitive to the competing reaction (Equation presented) and, when used with the k1 recommendation from Pirraglia et al. [27], are in good agreement with H 2/O2 explosion limit data in the intermediate temperature range of 700-900 K.
