RATE CONSTANTS FOR THE REACTIONS OF OH WITH CLO, CL2, AND CL2O AT 298K

The rate constants for the reactions of OH with CℓO, Cℓ2, and Cℓ2O at 298K have been determined in a discharge flow system using resonance fluorescence detection. The results are (9.1 ± 1.3) × 10−12, (5.5 ± 0.3) × 10−14, and (6.5 ± 0.5) × 10−12 (all in units of cm³ sec−1), respectively. In the reaction of OH and CℓO the reaction product HO2 has been detected indirectly, and a lower limit of 65% has been established for the OH + CℓO → HO2 + Cℓ channel.
