The rate of physisorption increases with

Rate of physisorption increase with

Rate of physisorption increases with decrease in temperature increase in temperature decrease in pressure decrease in surface area

Physisorption is

Rate of physisorption always increases with decrease in temperature. Explain.

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 statement(s) pertaining to the adsorption of a gas on a solid surface is(are) (i) adsorption is always exothermic (ii) physisorption may transform into chemsisorption transform into chemisorption at high temperature (iii) physisorption increases with increasing temperature but chemisorption decreases with increasing temperature . (iv) chemisorption is more exothermic than physisorption , however it is very slow due to higher energy of activation.
