As an instance of adsorption, chemisorption follows the adsorption process. The first stage is for the adsorbate particle to come into contact with the surface. The particle needs to be trapped onto the surface by not possessing enough energy to leave the gas-surface potential well. If it elastically collides with the surface, then it would return to the bulk gas. If it loses enough momentum through an inelastic collision, then it "sticks" onto the surface, forming a precursor s… WebAbsorption ist der Prozess, bei dem ein Fluid durch eine Flüssigkeit oder einen Feststoff (Absorbens) gelöst wird.
