Sulfuric acid is made by the contact process. A number of substances take part in this process, among them vanadium(V) oxide and water. What roles do vanadium(V) oxide and water have in the contact process?
- Avanadium(V) oxide: catalyst; water: reactant
- Bvanadium(V) oxide: catalyst; water: solvent
- Cvanadium(V) oxide: reactant; water: reactant
- Dvanadium(V) oxide: reactant; water: solvent
