CFC (chloro fluoro carbon) is very highly reactive in causing depletion of ozone layer in the atmosphere. Each atom of chlorine liberated from CFC is capable of decomposing ________________ molecules of ozone?
Correct answer: B. 105
- A. 102
- B. 105
- C. 109
- D. 1015
Explanation
Ultraviolet radiation releases chlorine radicals from CFCs, and the radicals repeatedly catalyse ozone destruction. A commonly quoted estimate is about 100,000 ozone molecules, or 10^5, per chlorine atom.
