Notes

Abstract: We present a kinetic study of the reactions of ground-state sodium atoms with the molecules CF₃Cl, CF₂Cl₂, CFCl₃, CF₃Br and SF₆ over the temperature range 644–918 K. Na(3²S(1/2)) was generated by the low-energy pulsed irradiation of NaI vapour above NaI solid at elevated temperatures in the presence of added reactants and monitored photoelectrically in the ‘single-shot mode’ by time-resolved atomic resonance absorption of the D lines at λ= 589 nm [Na(3²Pᴊ–3²S(1/2))], unresolved to ensure adherence to the Beer–Lambert law. The photoelectric signals were amplified without distortion, captured, digitised and stored in a transient recorder interfaced to a microcomputer for kinetic analysis. Absolute second-order rate constants for the reaction of sodium with these gases were determined at five temperatures within the overall temperature range, leading to the following Arrhenius parameters [k = A exp (-E/RT), errors 1 σ]: [graphic omitted]. These results, including data for CF₄, for which only an upper limit to the rate constant is presented, are compared with analogous results derived previously using sodium diffusion-flame measurements at single temperatures.
