Catalytic Properties
Which pair correctly represents a transition metal/compound used as catalyst and its process?
Select the correct option:
Solution
V2O5 - Contact process
In the Contact process for sulfuric acid manufacture, V2O5 catalyzes oxidation of SO2 to SO3. Haber process uses finely divided Fe, not Cu. Ostwald process primarily uses Pt-Rh gauze, not Fe2O3. Deacon process commonly uses CuCl2-based catalysts rather than NiO. Therefore, only V2O5 - Contact process is correctly matched.
