The uptake of NH3 and the heterogeneous reaction of NH 3 + HOBr → products on ice surfaces at 190 K have been investigated in a flow reactor coupled with a differentially pumped quadrupole mass spectrometer. The uptake coefficient γt for NH3 was determined to be (3.8 ±1.4) × 10-4 on ice films at 189.8 K, for a partial pressure of NH3 in the range of 7.0 × 10-7 to 3.8 × 10-6 torr. The amount of NH 3 uptake on the ice film was determined to be >2.9 × 10 15 molecules/cm2, based on the total ice surface area at 189.2 K. The heterogeneous reaction of NH3 + HOBr on ice surfaces has been studied at 190 K. The reaction probability γt was determined to be (5.3 ±2.2) × 10-4 and was found to vary insignificantly as HOBr surface coverage changes from 2.1 × 10 13 to 2.1 × 1014 molecules/cm2. A reaction pathway is proposed on the basis of experimental observations.
