Identify FALSE statement regarding adsorption from following.

Options

  1. AIt takes place due to unbalanced forces acting on the surface of solid or liquid.
  2. BDuring adsorption surface energy of adsorbent increases.
  3. CIt is caused by van der Waals forces.
  4. DIt is an exothermic process.

Correct answer

B. During adsorption surface energy of adsorbent increases.

Step-by-step solution
