Atmospheric chemistry: ozone reactions: physics and chemistry of the stratosphere

Typical exam questions

• Give the simple 2-step reaction that destroys ozone.
• What proof do we have that CFC's are the reason that we have stratospheric ozone depletion?
• Why is stratospheric ozone depletion primarily a problem at the South Pole and of lesser problem over the North Pole?
• Why is the North Polar region likely to experience less depletion than the South Pole but of more than mid-latitudes?
• Discuss the reasons the following statement is valid or invalid: "CFCs are not reactive, and so do not contribute to stratospheric ozone depletion".
