The rate of physisorption increases with

A

Decrease in temperature

B

Increase in temperature

C

decrease in pressure

D

Decrease in surface area

Text Solution

Verified by Experts

The correct Answer is:
A


Physical adsorption decreases with increase in temperature and vice versa at constant pressure. Physical adsorption is exothermic and it is favoured by a low temperature according to Le-Chatelier's principle.

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
