Write any two characteristics of Chemisorption. Ans: Pt and Pd form inert electrodes, i.e., they are not attacked by the ions of the electrolyte or the products of electrolysis. Hence, they are used as electrodes for carrying out electrolysis. 5.2. Why does physisorption decrease with the increase of temperature? Ans: Physisorption is an exothermic process : According to Le-Chatelier’s principle, if T is increased, equilibrium shifts in the backward direction i.e., gas is released from the surface of solid. 5.3. Why are powdered substances more effective as adsorbents than their crystalline form...
