Gas phase kinetics of the reactions of Na0 with H2, D2, H2O, and D2O

Article abstract of DOI:10.1063/1.453726

The gas phase reactions of the NaO radical with H2, D2, H2O, and D2O were studied in a flow tube reactor at room temperature.The reaction of NaO with H2 has two exothermic product channels, NaOH + H and Na + H2O.Both channels were observed and the Na formation channel produces some Na in the 3²P state.The rate constants for the abstraction channel for H2 and D2 reactants are (2.6+/-1.0) X 10^-11 and ( 1.1 X 0.4) X 10^-11 cm³ molecule^-1 s^-1 at 296+/-2 K.The reaction of NaO with H2O was shown to be second order and the products are assumed to be NaOH and OH.The rate constants for H2O and D2O reactants are (2.2+/-0.4) X 10^-10 and ( 1.2+/-0.2) X 10^-10 cm³ molecule^-1 s^-1 at 298+/-1 K.The measured NaO + H2O rate constant is compared to the predicted collision rate constant from a model based on the large attractive dipole-dipole force between NaO and H2O.The role of these reactions in mesospheric Na chemistry is briefly discussed.
