Vanadium pentoxide, V2O5, is used industrially as a catalyst in the
- A. Haber process
- B. hydrogenation of vegetable oils
- C. Contact process for making sulphuric acid
- D. cracking of long chain alkanes
Explanation
Vanadium pentoxide catalyses the oxidation of sulphur dioxide to sulphur trioxide, working by being reduced and then reoxidised in a cycle, which is a classic use of variable oxidation state. Iron is the catalyst for the Haber process and nickel for hydrogenation. Cracking uses zeolites, which are aluminosilicates rather than transition metal oxides.
