Ozone destroying reaction is O3+O→  2O2This ozone destroying reaction can be due to    I. NO          II. CFCs               III. N2                  Select the correct set of gases,

O3+UV radiation  →O2+O O3+O→2O2,ΔH=−390.0kJ In this process, heat is released into the atmosphere, NO also depletes  O3layerNO+O3→NO2+O2 NO2+O→NO2+O2 -------- O3+O→2O2NO is produced by combustion in supersonic jets operating in the stratosphere. CFCs (chlorofluorocarbons as Freon's) are being used as refrigerants and  aerosols. They have very long lifetime and rise to the stratosphere in low concentrations, where they can absorb UV radiation and dissociate.
