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

Options

  1. ABoth A and R are correct and R is the correct explanation of A .
  2. BBoth A and R are correct and R is not the correct explanation of A .
  3. CA is correct but R is incorrect.
  4. DA is incorrect but R is correct.

Correct answer

C. A is correct but R is incorrect.

Step-by-step solution

Finely divided charcoal has larger surface area and greater adsorption. Hence, it is more effective as an adsorbent. So, Assertion (A) is correct and Reason (R) is incorrect.
