Environmental Chemistry Question 5
Question 5 - 30 January - Shift 1
Formation of photochemical smog involves the following reaction in which $A, B$ and $C$ are respectively.
(i) $NO_2 \xrightarrow{\text{ hu }} A+B$
(ii) $B+O_2 \to C$
(iii) $A+C \to NO_2+O_2$
Choose the correct answer from the options given below:
(1) $O, NO \& NO_3^{-}$
(2) $O, N_2 O \& NO$
(3) $N, O, \& O_3$
(4) $NO, O \& O_3$

Answer: (4)
Solution:
Formula: Photochemical Smog
$NO_2 (g) \xrightarrow{hv} NO + O (g) $
$O (g) +O _{2} (g) \rightarrow O _{3} (g) $
$NO_g+O _{3} (g) \longrightarrow NO _{2} (g) +O _{2} (g) $
