Adsorption is the tendency of accumulation of molecular species at the surface of solid or liquid. Depending upon the nature of bonds or forces of attraction between adsorbate and adsorbent. It is classofied between physisorption and chemisorption. Which of the following statements are correct? (More than one correct)A. Adsorption always leads to a decrease in enthalpy and entropy of the system.B. Adsorption arises due to unsaturation in the enthalpy of valency force of atoms or molecules on the surface.C. Adsorption increases with rise in temperature.D. Adsorption decreases the surface energy.
