Gas phase chemistry of acid rain
In the gas phase sulfur dioxide is oxidized by reaction with the hydroxyl radical via an intermolecular reaction [5]:
SO2 + OH· → HOSO2·
which is followed by:
HOSO2· + O2 → HO2· + SO3
In the presence of water, sulfur trioxide (SO3) is converted rapidly to sulfuric acid:
SO3 (g) + H2O (l) → H2SO4 (l)
Nitrogen dioxide reacts with OH to form nitric acid:
NO2 + OH· → HNO3
Thus: NO2 and SO2
sulfur dioxide
