Which one of the following is not a property of physical adsorption?

Which one of the following is not a property of physical adsorption?

Options

  1. AHigher the pressure, more the adsorption
  2. BGreater the surface area, more the adsorption
  3. CLower the temperature, more the adsorption
  4. DUnilayer adsorption occurs

Correct answer

D. Unilayer adsorption occurs

Step-by-step solution

Physical adsorption increases with an increase in pressure. It also increases with the surface area. As adsorption is exothermic process so as temperature decreases, adsorption increases. It is a multilayer adsorption.
