Kinetics of the reactions of NO3 radicals with Cl and ClO

摘要: Rate coefficients for the reactions Cl + NO3 ClO NO2 (2) and products (3) were determined from observation of kinetic behavior in modulated photolysis Cl2-ClONO2-N2 mixtures at 1 atm pressure temperature range 278-338 K. was monitored absorption lambda = 662 nm formation reaction 2 indicated by characteristic spectrum ASII withdraws XSII system. The results gave k2 (5.5 +/- 2.0) x 10 cmT molecule s independent k3 (1.6 1.6/0.8) S exp(-(420 200)/T) molecule: . relative importance channels forming ClOO OClO 3 is discussed.
