Answer:
Explanation:
Chemical Adsorption or Chemisorption
It is due to strong chemical forces between adsorbate and adsorbent.
Characteristics:
- Nature of forces: Strong chemical forces
- Specificity: Highly specific nature
- Reversibility: It is irreversible
- Layer: It is a single layered process
- Enthalpy of adsorption: High enthalpy of adsorption [40 – 400 KJ/mole]
- The energy of activation: Very high
- Desorption: Very difficult
- Factors affecting: Surface area of adsorbent, nature of adsorbate Temperature.
