Question

Assertion (A): Finely divided charcoal can act as an adsorbent
Reason (R): Finely divided material has small surface area

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
• B. Both (A) and (R) are correct but (R) is not the correct explanation of (A)
• C. (A) is correct but (R) is incorrect
• D. (A) is incorrect but (R) is correct

Hint:

Adsorbents are more effective with large} surface area.
Be cautious about reason statements in assertion-reason questions.

Answer 1

The Correct Option is C

- Charcoal acts as a good adsorbent because it has a large surface area, not small. - Adsorption increases with surface area. - Thus, Assertion (A) is true but Reason (R) is incorrect.
