What is the primary difference between chemisorption and physisorption?

Step 1: Understand that both chemisorption and physisorption are ways that molecules attach to surfaces.
Step 2: Know that chemisorption involves strong chemical bonds between the surface and the molecules.
Step 3: Realize that because of these strong bonds, chemisorption is often irreversible, meaning the molecules do not easily come off the surface.
Step 4: On the other hand, physisorption involves weaker forces, like van der Waals forces, which are not as strong as chemical bonds.
Step 5: Since the forces in physisorption are weak, this process is reversible, meaning the molecules can easily detach from the surface.
