To determine which statement is not correct regarding physical adsorption, we will analyze each option based on the characteristics of physical adsorption. ### Step-by-Step Solution: 1. **Understanding Physical Adsorption:** - Physical adsorption, also known as physisorption, occurs due to weak Van der Waals forces between the adsorbate (the substance being adsorbed) and the adsorbent (the surface on which adsorption occurs). 2. **Analyzing Each Statement:** ...
