Which of the following statements is/are correct?a)Physical adsorptio...
Physical Adsorption:
- Physical adsorption is multilayer, non-directional, and non-specific in nature. This means that multiple layers of adsorbate molecules can be formed on the surface, the forces involved are not specific to the adsorbate, and the molecules are not aligned in a particular direction.
Chemical Adsorption:
- Chemical adsorption, on the other hand, is specific and involves the formation of chemical bonds between the adsorbate and the adsorbent surface. This type of adsorption increases with an increase in temperature due to the higher energy available for bond formation.
Solvent Preference:
- In some cases, solvent may be adsorbed in preference to the solute. This can occur when the solvent molecules have a stronger affinity for the adsorbent surface compared to the solute molecules.
Surface Energy:
- As a result of adsorption, there is an increase in surface energy. This is because the adsorbate molecules are held on the surface by attractive forces, leading to a higher energy state compared to the bulk material.
