Current Question (ID: 17833)

Question:

$\text{A gas that is not a common component of photochemical smog is-}$

Options:

1. $\text{Ozone}$
2. $\text{Acrolein}$
3. $\text{Peroxyacetyl nitrate}$
4. $\text{Chlorofluorocarbons}$

Solution:

$\text{HINT: CFCs cause ozone layer depletion.}$ $\text{Explanation:}$ $\text{Photochemical smog is a type of smog produced when ultraviolet light from the sun reacts with nitrogen oxides in the atmosphere. It is visible as a brown haze, and is most prominent during the morning and afternoon.}$ $\text{Occurs in a warm, dry, and sunny climate. A mixture of formaldehyde, acrolein, nitric oxide, ozone, and peroxy-acetyl nitrates (PAN)}$ $\text{Photochemical smog formation -}$ $\text{Emission of nitrogen oxides and hydrocarbons from automobiles exhausts and solar energy by the chain of reactions.}$ $\text{NO}_2(g) \rightarrow \text{NO}(g) + \text{O}(g)$ $\text{O}(g) + \text{O}_2 \rightleftharpoons \text{O}_3(g)$ $\text{NO}(g) + \text{O}_3(g) \rightarrow \text{NO}_2(g) + \text{O}_2(g)$ $3 \text{CH}_4 + 2 \text{O}_3 \rightarrow 3 \text{CH}_3 = \text{O(formaldehyde)} + 3\text{H}_2\text{O}$
