Abstract:

Rate constants and product distributions have been measured for a number of simple molecules reacting with ONOO- at 200 and 300K. NO, CO, H2, CH4, N2O, and H2O did not react with ONOO-. HCl and HCN underwent proton transfer in addition to other competing channels. Charge transfer from ONOO- was observed exclusively with O3 and NO2. SO2 and HCl underwent exchange for NO in ONOO-. HCN was the only substance to show substantial chemistry, producing CNO- and NO2- in addition to the proton transfer channel. Rate constants for the reactive substances were generally rapid, occurring at 10 of the collision rate constant.
