Formation of ClNO2 and HONO in the presence of NO2, O3 and wet NaCl aerosol
Abstract
The sticking coefficient of N2O5 on NaCl aerosol alpha=0.032+/-0.003 is determined at 292.3+/-0.5K and various relative humidities, considering the decrease of the aerosol diameter during the reaction. The rate constant ratio for the consecutive chemical reaction leading to ClNO2 (a) or 2 HNO3 (b) is determined to be ka/kb=2.5+/-0.7. For a solution of 18 weight percent NaCl and pH values above 2 the ratio is independent of pH and decreases for low pH.
