Mechanism of Adsorption
Answers
Answer:
Explanation:
The amount of heat evolved when one mole of the adsorbate is adsorbed on adsorbent is called enthalpy of adsorption. Adsorption is an exothermic process and enthalpy change is always negative.
When adsorbate molecules are adsorbed on the surface, freedom of movement of molecules become restricted and this results in decrease in entropy.
Adsorption is a spontaneous process at constant pressure and temperature, thus Gibb’s free energy is also decreased.
Answer:
Adsorption
Adsorption is the deposition of molecular species onto the surface. It differs from absorption which is a physical or chemical phenomenon in which atoms, molecules or ions enter some bulk phase. Let us know more about Absorption and its significance.
Mechanism of Adsorption
It is an exothermic process which means that energy is liberated during this process. The amount of heat that gets evolved when one mole of the adsorbate is adsorbed on adsorbent is known as enthalpy. At constant temperature and pressure, adsorption occurs spontaneously.
