The answer to question 2 seems to be incorrect. The explanation is as follows: Physical adsorption refers to the adsorption that occurs between the adsorbate and the adsorbent due to intermolecular forces (Van der Waals forces). Chemical adsorption: refers to the chemical reaction that occurs between the adsorbent and the adsorbate, driven by chemical bond forces.
