Which of the following statements is not true? a. Both physisorption and chemisorption are exothermic. b. Physisorption occurs with increase of free energy. c. Physisorption requires low activation energy but chemisorption requires high activation energy. d. The magnitude of chemisorption increases and that of physisorption decreases with rise in temperature.

The correct statements pertaining to the adsorption of a gas on a solid surface are (i) Adsorption is always exothermic (ii) Physisorption may transform into chemisorption at high temperature (iii) Physisorption increases with increasing temperature but chemisorotion decrease with increasing temperature (iv) Chemisorption is more exothermic than physisoption, however, it is very slow due to higher energy of activation
