  1. MM S4 K12 Present information from secondary sources to write the equations to show the reactions involving CFCs and ozone to demonstrate the removal of ozone from the atmosphere. CFCs are stable and are long lasting. They slowly migrate to the stratosphere. In the stratosphere… CFCl3 (+uv)  CF • + Cl •

  2. MM S4 K12 Present information from secondary sources to write the equations to show the reactions involving CFCs and ozone to demonstrate the removal of ozone from the atmosphere. Once the chlorine radical has been generated Cl• + O3  ClO • + O2 ClO • + O •  Cl • + O2 O3 + O • 2O2

  3. MM S4 K12 Present information from secondary sources to write the equations to show the reactions involving CFCs and ozone to demonstrate the removal of ozone from the atmosphere. It seems like that’s it….. but no, wait.. What’s this?

  4. MM S4 K12 Present information from secondary sources to write the equations to show the reactions involving CFCs and ozone to demonstrate the removal of ozone from the atmosphere. Once the chlorine radical has been generated Cl• + O3  ClO • + O2 ClO • + O •  Cl • + O2 Disaster.. It happens again

  5. MM S4 K12 Present information from secondary sources to write the equations to show the reactions involving CFCs and ozone to demonstrate the removal of ozone from the atmosphere. Once the chlorine radical has been generated Cl• + O3  ClO • + O2 ClO • + O •  Cl • + O2 And again

  7. MM S4 K12 Present information from secondary sources to write the equations to show the reactions involving CFCs and ozone to demonstrate the removal of ozone from the atmosphere. Once the chlorine radical has been generated Cl• + O3  ClO • + O2 ClO • + O •  Cl • + O2 And again. For about 100,000 times for every Cl • radical The net result is the destruction of huge amounts of ozone in the stratosphere because the chlorine radical is regenerated and acts as a catalyst.
