What is the primary mechanism of adsorption in physisorption?
Correct Answer: Weak Van der Waals forces
- Step 1: Understand that physisorption is a type of adsorption.
- Step 2: Know that adsorption means molecules stick to a surface.
- Step 3: Learn that physisorption involves weak interactions.
- Step 4: Identify the specific weak forces involved, which are called Van der Waals forces.
- Step 5: Conclude that the primary mechanism of physisorption is these weak Van der Waals forces.
