Given below, catalyst and corresponding process/ reaction are matched. The mismatch is
- A$\left[\mathrm{RhCl}\left(\mathrm{PPh}_3\right)_2\right]:$ Hydrogenation
- B$\mathrm{TiCl}_4+\mathrm{Al}\left(\mathrm{C}_2 \mathrm{H}_5\right)_3:$ Polymerization
- Correct answerC$\mathrm{V}_2 \mathrm{O}_5:$ Haber-Bosch process
- Dnickel : Hydrogenation.
Solution
Haber-Bosch process is used for the synthesis of ammonia.
$$
\mathrm{N}_2+3 \mathrm{H}_2 \rightleftharpoons 2 \mathrm{NH}_3 ; \Delta H=-92.0 \mathrm{~kJ}
$$
The best catalyst for this reaction is highly porous finely divided iron containing small amounts of promoters usually molybdenum or oxides of potassium and aluminium.
Hence, the correct answer is option: 'C'.
