Temperature and Pressure Dependent Rate Coefficients for the Reaction of Hg with Cl and the Reaction of Cl with Cl: A Pulsed Laser Photolysis-Pulsed Laser Induced Fluorescence Study

摘要: A pulsed laser photolysis-pulsed induced fluorescence technique has been employed to study the recombination of mercury and bromine atoms, Hg + Br M → HgBr (1) self-reaction Br2 (2). Rate coefficients were determined as a function pressure (200−600 Torr) temperature (243−293 K) in nitrogen buffer gas helium at room temperature. For reaction 1, kinetic measurements performed under conditions which atoms reactant excess concentration while simultaneously monitoring both bromine. dependent expression (1.46 ± 0.34) × 10-32 (T/298)-(1.86±1.49) cm6 molecule-2 s-1 was for third-order rate coefficient gas. The effective second-order 1 atmospheric is factor 9 smaller than previously recently published ...
