Ozone depletion Flashcards
1
Q
Why is the ozone layer beneficial?
A
Because it absorbs UV radiation
2
Q
use equations to explain how chlorine atoms catalyse decomposition of ozone
A
Cl* + O3 → ClO* + O2
ClO* + O3 → 2O2 + Cl*
2O3 → 3O2
Chlorine atoms catalyse the decomposition of ozone and contribute to the hole in the ozone layer.
3
Q
Why are CFCs bad?
A
because the form chlorine radicals which catalyse ozone depletion.
