- Ozone Depletion
- Cl Radicals
- Initiation
- CFCl3 --> Cl(rad) + CFCl2(rad)
- Propagation 1
- Cl(rad) + O3 --> ClO(rad) + O2
- Propagation 2
- ClO(rad) + O --> Cl(rad) + O2
- Initiation
- NO Radicals
- Propagation 1
- NO(rad) + O3 --> NO2(rad) + O2
- Propagation 2
- NO2(rad) + O --> NO(rad) + O2
- Propagation 1
- Nitrogen Oxide is made when lightening strikes, or from aeroplane engines
- CFCs were first used in refrigerators, or aerosol propellants as they had non-flammable desirable properties
- They may take decades to reach the ozone layer, however once there they are split by UV radiation to form chlorine radicals which deplete the ozone layer
- Call for regulation of CFCs was put into action by the Montreal Protocol which phases out CFC use
- Cl Radicals
