Match the catalyst with the correct process and choose the correct option.
| Catalyst | Process |
| (a) TiCl3 (Ziegler Natta) | (i) Production of polythene |
| (b) V2O5 | (ii) Contact process |
| (c) MnO2 | (iii) To decompose KClO3 to O2 |
| (d) Fe | (iv) Haber process |
Answer & explanation
Correct answer: option 2
Many of the d block elements and their compounds act as catalysts in various reactions.
V2O5 is used in contact process for the manufacture of H2SO4.
TiCl3 (Ziegler Natta catalyst) is used in production of polythene.
MnO2 is used to decompose KClO3 to O2.
Fe is used in Haber process.
