Which one of the following characteristics is not correct for physical adsorption?

Options

  1. AAdsorption increases with incresae in temperature
  2. BAdsorption is spontaneous
  3. CBoth enthalpy and entropy of adsorption are negative
  4. DAdsorption on solids is reversible

Correct answer

A. Adsorption increases with incresae in temperature

Step-by-step solution

As adsorption is an exothermic process. Rise in temperature will decrease adsorption.
