An Intiative by Sri Chaitanya

During adsorption there will be an increase in residual forces on the molecules.

The extent of adsorption per unit mass of adsorbent will remain same even on changing surface area of same mass of adsorbent.

When equilibrium is attained in adsorption then due to adsorption of gas at equilibrium entropy of system and entropy of surrounding both increase by the same amount.

Adsorption of gas on a solid surface is an entropy driven process.

Detailed Solution

Even on shifting surfaces with the same quantity of adsorbent, the extent of adsorption per unit mass of adsorbent will not change.
When adsorption equilibrium is reached, the entropy of the system and its surroundings both rise by the same amount as a result of the gas being absorbed at equilibrium.
Entropy is the driving force behind the adsorption of gas onto a solid surface.
