Several factors can influence the extent and nature of physisorption:
1. Surface Area: Larger surface areas provide more sites for adsorption, enhancing physisorption. 2. Temperature: Lower temperatures favor physisorption due to reduced kinetic energy of the adsorbate molecules. 3. Pressure: Higher pressure increases the concentration of adsorbate molecules, promoting physisorption. 4. Nature of Adsorbate and Adsorbent: The physical and chemical properties of both the adsorbate and the adsorbent affect physisorption. Polar molecules, for example, may interact more strongly with polar surfaces.
