What to Focus On

  • Adsorption is a surface phenomenon.
  • Adsorbate: substance that gets adsorbed.
  • Adsorbent: solid that adsorbs the substance.

  • Adsorption: surface retention.
  • Absorption: uniform penetration into bulk.
  • Sorption: general term for both processes.

  • Greater surface area → more adsorption.
  • Easily liquefiable gases are more strongly adsorbed.
  • Adsorption decreases with rise in temperature.

Common Mistakes to Avoid

Physical adsorption and chemisorption are the same because both involve gas sticking to a solid surface.

Adsorption increases with temperature because higher temperature always increases molecular activity.

Freundlich isotherm applies at all pressures, so it can predict adsorption even at very high pressure.
