Q: What is the primary driving force for adsorption in physisorption?
Solution: Physisorption is primarily driven by weak van der Waals forces.
Steps: 4
Step 1: Understand what physisorption is. It is a process where molecules stick to a surface without forming strong chemical bonds.
Step 2: Learn about the forces involved in physisorption. The main forces are called van der Waals forces, which are weak attractions between molecules.
Step 3: Recognize that these van der Waals forces are the primary reason why molecules can attach to surfaces in physisorption.
Step 4: Conclude that the weak nature of van der Waals forces allows for easy attachment and detachment of molecules on surfaces.
