1.	Which of the following statements is not correct for chemisorption and physisorption ?
Answer» PHYSICAL ADSORPTION occurs at a low temperature and CHEMISORPTION occurs at all temperature Magnitude of chemisorption DECREASES with rise in temperature while physisorption INCREASES with rise in temperature . Chemisorption is irreversible and physisorption is reversible . In physisorption activation energy is low while in chemisorption it is high. Solution :Chemisorption increases and physisorption decreases with rise in temperature .
