The product branching ratio, α, for N2O formation in the reaction of NH2 with NO2 has been studied by mass spectrometry at seven temperatures between 300 and 990 K. The value of α was determined by kinetic modeling of the absolute yield of N2O. α was found to be 0.19 ± 0.02 without significant temperature dependence, assuming the total rate constant for NH2 + NO2 to be kt = 1.8 × 10-2 × T0.11 exp (+597/T) cm3/molecule · s in the temperature range studied. The effect of kt on α has been discussed.
