A KINETIC STUDY ON REACTIONS OF OBRO WITH NO, OCLO, AND CLO AT 298 K

Abstract Kinetics for reactions of OBrO with NO, OClO, and ClO were examined using discharge flow coupled with mass spectrometer (DF/MS) technique at 298 K and total pressure of 1 torr under the pseudo-first-order condition in which OBrO was a minor reactant. The rate constant for the reaction of OBrO with NO was determined to be k 2 =(1.77±0.32)×10 −12 cm 3 molecule −1 s −1 . NO 2 was found to be the product for OBrO+NO. The rate constants for OBrO reactions with OClO and ClO were estimated to be k 3 −14 and k 4 −13 cm 3 molecule −1 s −1 , respectively.
