N2 - Rates of the reactions S2 + O → SO + S (10), S2 + O2 → products (1), S2 + O3 → products (18), S2 + N2O → products (20), S2 + NO → products (21), S2 + NO2 → products (19) were investigated at 409 K and low pressure (0.89-3.0 Torr) in a discharge-flow system with mass spectrometric detection. Reaction 10 was found to be fast with k10 = (1.12 ± 0.20) × 10-11 cm3 molecule-1 s-1. Under the experimental conditions, S2 did not react with O2, O3, N2O, NO, or NO2. Upper limits for the rate constants of these reactions are k1 < 2.3 × 10-19, k18 < 4.0 × 10-15, k20 < 3.2 × 10-17, k21 < 8.5 × 10-17, and k19 < 1.1 × 10-15 cm3 molecule-1 s-1. Reaction 10 produced a large ion current at m/e 48 leading to the conclusion that S2 + O produces SO + S as primary products.
