To determine which type of adsorption, physisorption or chemisorption, has a higher enthalpy of adsorption, we can follow these steps: ### Step 1: Define Physisorption and Chemisorption - **Physisorption**: This type of adsorption involves weak van der Waals forces between the adsorbate (the substance being adsorbed) and the adsorbent (the surface on which adsorption occurs). These forces are relatively weak and non-specific. - **Chemisorption**: This type involves the formation of strong chemical bonds (covalent or ionic) between the adsorbate and the adsorbent. These bonds are much stronger than the forces involved in physisorption. ### Step 2: Compare the Nature of Forces - In physisorption, the forces are weak, leading to lower energy changes during the adsorption process. ...
