The correct Answer is:
To solve the given question, we need to evaluate the Assertion (A) and the Reason (R) provided, and determine their validity and relationship. ### Step 1: Evaluate the Assertion (A) The assertion states: "Activated adsorption is also known as chemical adsorption or chemisorption." - **Analysis**: This statement is true. Activated adsorption refers to the process where the adsorbate forms strong chemical bonds with the adsorbent, which is characteristic of chemisorption. ### Step 2: Evaluate the Reason (R) The reason states: "It involves formation of chemical bonds between adsorbent and reactants." - **Analysis**: This statement is also true. Chemisorption involves the formation of chemical bonds between the adsorbate (the substance being adsorbed) and the adsorbent (the surface on which adsorption occurs). This bond formation is what distinguishes chemisorption from physisorption, where only weak van der Waals forces are involved. ### Step 3: Determine the Relationship Now we need to check if the reason explains the assertion. - Since the reason (R) accurately describes the process of chemisorption and supports the assertion (A) that activated adsorption is indeed chemisorption, we can conclude that the reason provides a correct explanation for the assertion. ### Conclusion Both the assertion and the reason are true, and the reason correctly explains the assertion. Thus, the correct choice is: **Option 1: Both A and R are true and R is the correct explanation of A.** ---
