摘要: Abstract The effect of CO and SO 2 on the rate photolysis part per million concentrations gaseous nitrous acid in N -O mixtures has been studied. photolyses were conducted at atmospheric pressure room temperature (294 ± K) a flow system. results give information several competing reactions hydroxyl radical which is produced by photodissociation HNO . Rate constants for reactions: OH + NO M = (1) (M O 1 atm); H (3) HSO 3 (7) relative to constant (6) have determined. Based literature value k 6 1.5 × 10 −13 cm molecule −1 s values obtained are [M] 6.1 1.1 −12 , 2.2 0.2 7 6.0 0.8 units with atm. Comparison data those low pressures shows that both dependent region below Some implications these chemistry lower atmosphere briefly discussed.
