Troposheric Reactions and Pollution Topic 3 - Coggle Diagram

- - - - Photolysis (chemical rxn involving photons) of ozone
      - Photolysis of carbonyl compounds in the presence of
        NO
- - - - NO2 Production (Precursor of Ozone)
        
        Oxidation of NO that emitted by combustion sources NO + O3 = NO2 + O2, *O3 is used to produce NO2, so stationary phase is present for ozone
        
        Overall reaction: RH + 2NO + 2 O2 --> carbonyl + 2NO2 + H2O
        
        NO2 can be produced without consuming ozone (Disturbs stationery phase resulting net ozone production)
        
        RH: Reactive Hydrocarbon (can be a VOC compound)
    - - O + O2 --> O3 (Ozone)
        
        This accounts for 90% of the ozone in the troposphere. The
        remaining 10% comes from the stratosphere.
