Question

Of physisorption or chemisorptions, which has a higher enthalpy of adsorption? Why.

Open in App

Solution

Dear student ,

Chemisorption has higher enthalpy of adsorption. as in this type of adsorption chemical bonds are formed in between of adsorbate and adsorbent. as bond formed is stronger than physical adsorption (weak van der waal interaction) so more amount of energy is released.
