Match List - I with List - II.

List I
(Processes / Reactions)
List II
(Catalyst)
(A) 2SO$_2$(g) + O$_2$(g) $\to$ 2SO$_3$(g) (I) Fe(s)
(B) 4NH$_3$(g) + 5O$_2$(g) $\to$ 4NO(g) + 6H$_2$O(g) (II) Pt(s) $-$ Rh(s)
(C) N$_2$(g) + 3H$_2$(g) $\to$ 2NH$_3$(g) (III) V$_2$O$_5$
(D) Vegetable oil(l) + H$_2$ $\to$ Vegetable ghee(s) (IV) Ni(s)

Choose the correct answer from the options given below :

  1. A $$(\mathrm{A})-(\mathrm{III}),(\mathrm{B})-(\mathrm{I}),(\mathrm{C})-(\mathrm{II}),(\mathrm{D})-(\mathrm{IV})$$
  2. B $$(\mathrm{A})-(\mathrm{III}),(\mathrm{B})-(\mathrm{II}),(\mathrm{C})-(\mathrm{I}),(\mathrm{D})-(\mathrm{IV})$$ Correct answer
  3. C $$(\mathrm{A})-(\mathrm{IV}),(\mathrm{B})-(\mathrm{III}),(\mathrm{C})-(\mathrm{I}),(\mathrm{D})-(\mathrm{II})$$
  4. D $$(\mathrm{A})-(\mathrm{IV}),(\mathrm{B})-(\mathrm{II}),(\mathrm{C})-(\mathrm{III}),(\mathrm{D})-(\mathrm{I})$$

Solution

(A) $$2 \mathrm{SO}_{2}(\mathrm{g})+\mathrm{O}_{2}(\mathrm{g}) \stackrel{\mathrm{V}_{2} \mathrm{O}_{5}}{\longrightarrow} 2 \mathrm{SO}_{3}$$ <br/><br/> (B) $$4 \mathrm{NH}_{3}(\mathrm{g})+5 \mathrm{O}_{2}(\mathrm{g}) \stackrel{\mathrm{Pt}(\mathrm{s})-\mathrm{Rh}(\mathrm{s})}{\longrightarrow} 4 \mathrm{NO}(\mathrm{g})+6 \mathrm{H}_{2} \mathrm{O}(\mathrm{g})$$ <br/><br/> (C) $$\mathrm{N}_{2}(\mathrm{g})+3 \mathrm{H}_{2}(\mathrm{g}) \stackrel{\mathrm{Fe}(\mathrm{s})}{\longrightarrow} 2 \mathrm{NH}_{3}(\mathrm{g})$$ <br/><br/> (D) Vegetable oil(I) $+\mathrm{H}_{2} \stackrel{\mathrm{Ni(s})}{\longrightarrow}$ Vegetable ghee(s)
