Adsorption is an
Endothermic process
Exothermic Process
Both A & B
None of these
The heat of Adsorption -
An important factor with adsorption is the heat of adsorption. During adsorption, there is always a decrease in residual forces at the surface i.e. there is a decrease in surface energy which appears as heat., Heat is released during adsorption.
So, adsorption is an exothermic process.
Therefore, option (2) is correct.
