What is the primary process involved in adsorption? (2023)

Step 1: Understand that adsorption is a process where molecules (called adsorbates) stick to a surface (called adsorbent).
Step 2: Recognize that this sticking happens because of physical forces, like attraction, between the adsorbate and the adsorbent's surface.
Step 3: Remember that these forces are not chemical bonds; they are weaker interactions, such as van der Waals forces.
Step 4: Conclude that the primary process in adsorption is this physical attraction that allows the adsorbate to adhere to the adsorbent.
