Question

Formation of photochemical smog involves the following reaction in which $A , B$ and $C$ are respectively i $NO _2 \xrightarrow{ h\nu } A + B$ ii $B + O _2 \rightarrow C$ iii $A + C \rightarrow NO _2+ O _2$ Choose the correct answer from the options given below:

• A. $N , O _2 \& O _3$
• B. $NO , O \& O _3$
• C. $O , N _2 O \& NO$
• D. $O , NO \& NO _3^{-}$

Answer 1

Answer: (B)

$NO , O \& O _3$

Answer 2

NO2g​⟶hv​(A)NOg​​+(B)Og​​
(B)Og​​+O2g​⇌O3g​
(A)NOg​​+ (C) O3g​​⟶NO2g​+O2g​
