- BA-II, B-III, C-IV, D-I
- Correct answerCA-III, B-I, C-IV, D-II
- DA-III, B-IV, C-I, D-II
Solution
Ostwald's process :-
$$
4 \mathrm{NH}_3(\mathrm{~g})+5 \mathrm{O}_2(\mathrm{~g})
\stackrel{\text { Pt/Rh gauge catalyst }}{500 \mathrm{~K}, 9 \text { bar }}$$
$4 \mathrm{NO}(\mathrm{g})+6 \mathrm{H}_2 \mathrm{O}(\mathrm{g})$
Lead Chamber process:
$$
\begin{aligned}
& \mathrm{NO}+\frac{1}{2} \mathrm{O}_2 \rightarrow \mathrm{NO}_2 \\
& \mathrm{NO}_2+\mathrm{SO}_2 \rightarrow \mathrm{NO}+\mathrm{SO}_3 ; \mathrm{SO}_3+\mathrm{H}_2 \mathrm{O} \rightarrow \mathrm{H}_2 \mathrm{SO}_4
\end{aligned}
$$
Deacon's process :
$$
4 \mathrm{HCl}+\mathrm{O}_2 \underset{723 \mathrm{~K}}{\stackrel{\mathrm{CuCl}_2}{\longrightarrow}} 2 \mathrm{Cl}_2+2 \mathrm{H}_2 \mathrm{O}
$$
Haber's process :
$\mathrm{N}_2+3 \mathrm{H}_2 \underset{\mathrm{Fe}}{\stackrel{250 \mathrm{~atm}}{\rightleftharpoons}} 2 \mathrm{NH}_3$
Hence, the correct answer is option: 'C'.
