Answer : Activated adsorption
Explanation :
Let us consider the example of adsorption of $\;H_{2}\;$ gas on the surface of nickel or platinum . Due to unbalanced forces on the surface of the solid , the hydrogen molecules are attracted towards it by weak vanderwalls force and hence get adsorbed on it .
The adsorbed molecules then dissociate into atoms and are chemisorbed and hence some activation energy , the process is also called activated adsorption .
