Question

In the reaction \( 2\text{H}_2\text{O}_2 \rightarrow 2\text{H}_2\text{O} + \text{O}_2 \), what is the role of potassium iodide (KI) in this reaction?

• A. It acts as a catalyst.
• B. It acts as a reducing agent.
• C. It acts as an oxidizing agent.
• D. It decomposes to release iodine.

Hint:

Remember, a catalyst accelerates the rate of a chemical reaction without being consumed or permanently altered in the process.

Answer 1

The Correct Option is A

In the decomposition reaction of hydrogen peroxide, potassium iodide (KI) acts as a catalyst. It speeds up the reaction without being consumed in the process.
