Formation of photochemical smog involves the following reaction in which A, B, and C are respectively:
\(\text{NO}_2 \xrightarrow{h\nu} \text{A} + \text{B}\)
\(\text{B} + \text{O}_2 \rightarrow \text{C}\)
\(\text{A} + \text{C} \rightarrow \text{NO}_2 + \text{O}_2\)
Choose the correct answer from the options given below:
NO, O, and O3
N2O and NO
N, O2, and O3
O, NO, and NO3
Step 1: Breakdown of Reactions
Reaction (i): \(\text{NO}_2\) undergoes photodissociation under sunlight:
\[\text{NO}_2 \xrightarrow{h\nu} \text{NO (A)} + \text{O (B)}.\]
Reaction (ii): The oxygen radical (B) reacts with molecular oxygen to form ozone:
\[\text{O (B)} + \text{O}_2 \rightarrow \text{O}_3 (\text{C}).\]
Reaction (iii) \(\text{NO (A)}\) reacts with ozone to regenerate \(\text{NO}_2\) and molecular oxygen:
\[\text{NO (A)} + \text{O}_3 (\text{C}) \rightarrow \text{NO}_2 + \text{O}_2.\]
Step 2: Identify A, B, and C
From the reactions:
\(\text{A} = \text{NO}\) (Nitric oxide),
\(\text{B} = \text{O}\) (Oxygen radical),
\(\text{C} = \text{O}_3\) (Ozone).
Conclusion: The correct answer is (4) NO, O, and O\(_3\)
For a reaction, \[ {N}_2{O}_5(g) \rightarrow 2{NO}_2(g) + \frac{1}{2} {O}_2(g) \] in a constant volume container, no products were present initially. The final pressure of the system when 50% of the reaction gets completed is:
