Abstract: A kinetic study of the reaction Mg(1S) + N2O(X1-SIGMA+) --> k1 MgO(X1-SIGMA+) + N2(X1SIGMA(g)+) is carried out in the temperature range from 470 to 925 K. The kinetic data are obtained in a fast-flow reactor, and the magnesium atoms are generated by thermal evaporation from magnesium metal pellets. Atomic absorption spectroscopy at 285 nm is used as the detection technique. The influence of the experimental parameters such as the reactor pressure and initial magnesium absorbance on k1 has been verified, and the Arrhenius expression k1 = (1.4 +/- 0.3) x 10(-10) exp(-44.3 +/- 1.3 kJ mol-1/RT) cm3 molecule-1 s-1 is derived. This expression is discussed in view of the literature data on other alkali and alkaline earth metal/N2O reactions.
