WebJun 18, 2024 · The over all reaction between oxygen and ozone formation is: (4) 3 O 2 ⇌ 2 O 3. The absorption of UV B and C leads to the destruction of ozone. (5) O 3 + h ν → O + O 2. (6) O 3 + O → 2 O 2. A dynamic equilibrium is established in these reactions. The ozone concentration varies due to the amount of radiation received from the sun.
