Notes:
The rate constants of the reaction between OH and H2S in He, N2, and O2 over the temperature range 245-450 K have been determined using the discharge flow-resonance fluorescence technique. At 299 K, k1 = (4.4 ± 0.7) × 10-12 cm3 molecule-1 s-1. The temperature dependence of the rate constant can be fitted either by k1 = 5.6 × 10-12 exp(-57/T) or by k1 = (3.8 × 10-19)T2.43 exp(732/T) to within 8 and 9%, respectively. However, the non-Arrhenius behavior can be confidently confirmed. The absence of the pressure dependence and the third-body effect at low temperature suggest that the complex formation mechanism is not important over the temperature range of our study.
