Assertion : Reaction of SO ₂ and H ₂ ~S in the presence of Fe ₂ O ₃ catalyst gives elemental sulphur. Reason : SO ₂ is a reducing agent.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion
  3. CIf assertion is true but reason is false
  4. DIf both assertion and reason are false.

Correct answer

B. If both assertion and reason are true but reason is not the correct explanation of assertion

Step-by-step solution

SO ₂ shows both oxidising as well as reducing nature. The reaction given in assertion is due to oxidising nature of SO ₂ . 2 H ₂ ~S + SO ₂ 2 H ₂ O +3 ~S
