Key Concepts

Chemisorption

Chemisorption is an adsorption process where adsorbate molecules form strong chemical bonds with the surface, involving significant energy changes and specific activation energies. This differs from physisorption, which involves weaker van der Waals forces.

Heat of Adsorption

In chemisorption, the heat of adsorption is negative because energy is released when chemical bonds form between the adsorbate and the surface, reflecting the exothermic nature of the process.

Temperature Dependence

Chemisorption typically requires higher temperatures to provide the necessary activation energy for the formation of chemical bonds, distinguishing it from processes that can occur at lower temperatures.

Reversibility

Due to the strong chemical bonds formed during chemisorption, the process is usually irreversible or only weakly reversible, which contrasts with adsorption processes that involve physisorption where the adsorption and desorption are easily reversible.

Monolayer Formation

Chemisorption generally leads to the formation of a monomolecular layer because once the chemically active sites on the surface are occupied, further adsorption is typically prevented.
