Q: What is the main difference between physisorption and chemisorption?
Solution: The main difference lies in the nature of forces involved; physisorption is due to weak van der Waals forces, while chemisorption involves strong chemical bonds.
Steps: 4
Step 1: Understand that physisorption and chemisorption are two ways that molecules can attach to a surface.
Step 2: Learn that physisorption happens because of weak forces called van der Waals forces, which are like gentle attractions.
Step 3: Recognize that chemisorption involves strong chemical bonds, which are much stronger than the forces in physisorption.
Step 4: Remember that because of these differences, physisorption is usually reversible, while chemisorption is often not.
