Assertion: Reaction of SO2 and H2S in the presence of Fe2O3 catalyst gives elemental sulphur. Reason: SO2 is a reducing agent.

Question

Assertion: Reaction of SO2 and H2S in the presence of Fe2O3 catalyst gives elemental sulphur. Reason: SO2 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

H 2 S and SO 2 react as follows. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/d2d9420d43ea4232565f3d94a2cd94b1-.png" /> In this reaction SO 2 is oxidising agent and H 2 S is reducing agent. Thus, assertion is true but reason is false.

Q. Assertion : Reaction of $S O_{2}$ and $H_{2} S$ in the presence of $F e_{2} O_{3}$ catalyst gives elemental sulphur.
Reason : $S O_{2}$ is a reducing agent.

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

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

If assertion is true but reason is false

If both assertion and reason are false

$H_{2} S$ and $S O_{2}$ react as follows.

In this reaction $S O_{2}$ is oxidising agent and $H_{2} S$ is reducing agent.
Thus, assertion is true but reason is false.
