A single chlorine free radical can destroy how many ozone molecules ?
Correct answer: D. 100000
- A. 10
- B. 100
- C. 10000
- D. 100000
Explanation
A chlorine radical is regenerated in catalytic ozone-depletion cycles, allowing one radical to destroy approximately 100,000 ozone molecules before it is removed. Students may choose c, 10,000 molecules, by remembering the large catalytic effect but underestimating its approximate scale.

About Real and Ideal Gases
An ideal gas is modelled as particles with negligible volume and no intermolecular attraction, obeying Boyle's, Charles's and Avogadro's laws through PV = nRT. Real gases deviate from this behaviour, especially at high pressure and low temperature, because particle volume and attractive forces matter; the van der Waals equation explains these corrections.
