Question

V₂O₅ catalyst is used for the manufacture of ______.

Options

• HNO₃

• Polyethylene

• H₂SO₄

• NH₃

Answer 1

V₂O₅ catalyst is used for the manufacture of H₂SO₄.

Explanation:

Vanadium pentoxide (V₂O₅) is the primary catalyst used in the Contact Process for the industrial production of sulfuric acid. It facilitates the reversible oxidation of sulfur dioxide SO₂) into sulfur trioxide (SO₃), a critical step that would otherwise occur too slowly for commercial use. The reaction is represented by the equation: \[\ce{2SO2 + O2 \overset{V2O5}{->} 2SO3}\]
