Answer: chemical bonds.
- A weak van der Waals forces
- B chemical bonds
- C hydrogen bonds only
- D no bonds at all
Correct answer: B. chemical bonds
Explanation: Chemisorption involves genuine chemical bonds, so it is stronger and more specific than physisorption.
A typical adsorption isotherm: x/m (mass adsorbed per gram of adsorbent) rises steeply at low pressure, then flattens into a saturation plateau as the adsorbent surface fills up.
