Why is adsorption always exothermic?

Options

  1. AAdsorption is always endothermic, not exothermic.
  2. BAdsorption involves the release of energy, making it exothermic.
  3. CAdsorption and exothermicity are unrelated.
  4. DAdsorption can be either endothermic or exothermic depending on the conditions.

Correct answer

B. Adsorption involves the release of energy, making it exothermic.

Step-by-step solution

Correct Option is : (B) Adsorption involves the release of energy, making it exothermic.
