Question
Explain how the adsorption of gas on solid varies with the surface area of adsorbent.
Short Note
Solution
Surface area of the adsorbent:
- Adsorption is a surface phenomenon. Hence, the extent of adsorption increases with an increase in the surface area of the adsorbent.
- Finely divided substances, rough surfaces, colloidal substances are good adsorbents as they provide a larger surface area for a given mass.
