To solve the question regarding the assertion and reason provided, let’s break it down step by step. ### Step 1: Analyze the Assertion (A) **Assertion (A)**: Physical adsorption of molecules on the surface requires activation energy. - **Explanation**: Physical adsorption, also known as physisorption, occurs due to weak van der Waals forces between the adsorbate (the molecules being adsorbed) and the adsorbent (the surface). These interactions do not involve significant energy changes or electron transfer. Therefore, physical adsorption does not require activation energy. ### Step 2: Analyze the Reason (R) ...
