Surface Chemistry – Solutions
1) Give reason why a finely divided substance is more effective as an adsorbent.
A finely divided substance is more effective as an adsorbent as it provides a greater surface area as compared to its crystalline form. The greater surface area of an adsorbent, the greater is the extent of adsorbent as adsorption is a surface phenomenon.
2) What are the factors that influence the adsorption of a gas on a solid?
The extent of adsorption o a gas on a solid surface depends on the following factors:
i) Nature of gas
ii) Surface area of adsorbent
