Question

Why is vanadium oxide used as a catalyst in the production of sulphuric acid? a) It acts as a reducing agent.

b) It provides energy for the reaction.

c) It acts as a catalyst for the oxidation of sulfur dioxide.

d) It forms sulfuric acid directly.

Answer 1

Vanadium oxide is used as a catalyst in the production of sulfuric acid because it acts as a catalyst for the oxidation of sulfur dioxide.

Step-by-step explanation:

Vanadium oxide is used as a catalyst in the production of sulfuric acid because it acts as a catalyst for the oxidation of sulfur dioxide (c). In the Contact Process, sulfur dioxide gas is passed together with air over a solid vanadium(V) oxide catalyst. The vanadium(V) oxide helps increase the rate of the reaction by lowering the activation energy, making the production of sulfuric acid more efficient.
