The effect of water in the reaction of NaCl with NO2 was investigated by diffuse reflectance infrared spectroscopy. The growth of NO3- absorption showed first order reaction of P(NO2) for water preadsorbed NaCl while the dry reaction of NaCl-NO2 was quadratic. The absorption between 1300 and 1500cm-1 following the process of H20-evacuation-NO2-evacuation-H2O-evacuation-NO2, demonstrated that, after cease of NO3- formation, the exposure to humidity reproduced a fresh H2O adsorbed NaCl surface.
