Question

Adsorption isobars of chemisorption and physisorption are of the same type.

• A. True
• B. False

Answer 1

The correct option is B False

Adsorption isobars of chemisorption and physisorption are of different type. They are the plots of extent of adsorption (x/m) versus temperature at constant pressure. In case of physisorption, with increase in temperature, the extent of adsorption decreases. In case of chemical adsorption, with increase in temperature, the extent of adsorption decreases.
