Question

The common components of photochemical smog are:

• A. \( O_3, CH_4, CO_2 \)
• B. \( O_3, CO_2, CO \)
• C. \( O_3, SO_3, PAN \)
• D. \( O_3, NO, PAN \)

Hint:

Photochemical smog is a complex mixture of pollutants that forms when sunlight reacts with pollutants such as NO and hydrocarbons. Ozone is a key component.

Answer 1

The Correct Option is D

Photochemical smog is formed by the reaction of sunlight with pollutants such as nitrogen oxides and volatile organic compounds. The most common components of photochemical smog are ozone (\( O_3 \)), nitrogen oxides (\( NO \)), and peroxyacetyl nitrates (PAN), which are formed under high-temperature conditions, especially in the presence of sunlight.
