Decomposition of Ozone

2O₃ → 3O₂

Обзор

Ozone decomposes into molecular oxygen. In the stratosphere, this reaction is part of the ozone-oxygen cycle that protects Earth from UV radiation. CFCs catalyze this decomposition, leading to ozone layer depletion, which was the subject of the Montreal Protocol.
