Atomic Resonance Fluorescence for Rate Constants of Rapid Bimolecular Reactions
Alternative Title
Part 7. Sulphur atom reactions: S+O₂ → SO+O and S+NO₂ → SO+NO from 296 to 410 K
Abstract
Detection of S 3PJ atoms in a flow system, using atomic resonance fluorescence at 181 nm, has been used to determine the rate constants k1 and k2/cm3 s-1 for reactions (1) and (2): S+O2→k1 SO+O; (1) S+ NO 2→K2SO+NO. (2) Pseudo first-order conditions were used wih [O2]0/[S]0 and [NO2] 0/[S]0 ≫ 1. Measurements of k1 and k 2 from 296 to 410 K gave the following Arrhenius expressions: k 1 = (1.7 ± 0.5) × 10-12 exp (+(153 ± 108)/T) cm3 s-1; (2σ) and k2 = (4.9 ± 1.0) × 10-11 exp (+(84 ± 60)/T) cm3 s-1. (2σ).
