Assertion (A) Finely divided charcoal can act as an adsorbent. Reason (R) Finely divided material has small surface area.
  1. Both $A$ and $R$ are correct and $R$ is the correct explanation of $A$.
  2. Both $\mathrm{A}$ and $\mathrm{R}$ are correct and $\mathrm{R}$ is not the correct explanation of $\mathrm{A}$.
  3. $A$ is correct but $R$ is incorrect.
  4. $A$ is incorrect but $\mathrm{R}$ is correct.

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.
