Question

Reaction of $SO_2$ and $H_2S$ in the presence of $Fe_2O_3$ catalyst gives elemental sulphur. $SO_2$ is a reducing agent.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (C)

If assertion is true but reason is false

Answer 2

$H _{2} S$ and $SO _{2}$ react as follows. In this reaction $SO _{2}$ is oxidising agent and $H _{2} S$ is reducing agent. Thus, assertion is true but reason is false.
