Question

Role of Adsorption in Surface Chemistry

Answer 1

Answer:

Explanation:

Accumulation of species on higher concentration on the surface of a substance due to intermolecular force is known as adsorption. For Example, gases such as H2, O2, N2 adsorbs on the surface of activated charcoal.

Enthalpy of Adsorption: Amount of heat energy liberated when one mole of gas is adsorbed on the unit surface area of adsorbent is known as enthalpy of adsorption

Answer 2

Adsorption is the adhesion of atoms, ions or molecules from a gas, liquid or dissolved solid to a surface. This process creates a film of the adsorbate on the surface of the adsorbent. For Example, gases such as H2, O2, N2 adsorbs on the surface of activated charcoal.
