Question

Match the following:
List-I (Reaction)

• A) Hydrogenation of vegetable oils
• B) Decomposition of potassium chlorate
• C) Oxidation of SO₂ in lead chamber process
• D) Oxidation of ammonia in Ostwald’s process

List-II (Catalyst)

• I) Ni
• II) MnO₂
• III) Pt
• IV) NO(g)

• A. A-II, B-IV, C-I, D-III
• B. A-I, B-II, C-IV, D-III
• C. A-III, B-IV, C-I, D-II
• D. A-III, B-II, C-IV, D-I

Hint:

In catalysis-based matching, remember: - Ni for hydrogenation, - MnO\(_2\) for decomposition of chlorates, - NO for lead chamber oxidation, - Pt for Ostwald's process.

Answer 1

The Correct Option is B

Step 1: Match reactions to their correct catalysts

• A) Hydrogenation of vegetable oils — Ni is used as catalyst. I
• B) Decomposition of potassium chlorate — MnO₂ is used as catalyst. II
• C) Oxidation of SO₂ in lead chamber process — NO(g) acts as catalyst. IV
• D) Oxidation of ammonia in Ostwald’s process — Pt is used as catalyst. III

Step 2: Arrange according to option format

\[ \text{A-I, B-II, C-IV, D-III} \]

Final Answer:

A-I, B-II, C-IV, D-III
