The total rate constant for the NH2 + NO reaction has been measured in the temperature range 305-1037 K using a laser photolysis mass spectrometric technique by probing the rates of H2O formation and NO decay. A weighted least-squares analysis of our data gives the following total rate constant expression : k(t) = 8.29 x 10(13)T(-0.57) exp(300/T) cm(3)/(mol s). The branching ratios for the two product channels of the NH2 + NO reaction, N2H + OH (alpha) and N-2 + H2O (beta), have also been measured in the temperature range 300-1200 K by detecting CO2 (formed by the reaction of OH as the added CO) and NO for alpha and H2O for beta. The value of or was found to increase gradually from 0.1 at 300 K to 0.28 at 1000 K, with a concomitant decrease in beta from 0.9 at 300 K to 0.72 at 1000 K. At temperatures between 1000 and 1200 K, alpha rapidly increases to 0.47 according to the result of our modeling of observed NO decay rates. The drastic upturn in the value of alpha above 1000 K confirms the results of our recent study of the NH3 + NO reaction by FTIR spectrometry as well as the conclusion reached by modeling of NH3-NO flame speeds that alpha greater than or equal to 0.5 above 1500 K. The absolute rate constants of the two branching reactions are recommended for future applications over the temperature range 300-2000 K.
