Assertion: Reaction of SO(2) and H(2)S i...

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.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion

B

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

C

If assertion is true but reason is false

D

If the assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
B
`SO_2` shows both oxidising as well as reducing nature. The reaction given in assertion is due to oxidising nature of `SO_2`.
`2H_2 S + SO_2 to 2H_2 O + 3S`
