1.	Which of the following statements is true with respect to the types of adsorption?(a) Chemisorption is stronger than physisorption(b) Physisorption is stronger than chemisorption(c) They are both equal(d) They cannot be comparedThis question was addressed to me in an online quiz.I need to ask this question from Surface Chemistry topic in chapter Surface Chemistry of Chemistry – Class 12
Answer» The correct answer is (a) CHEMISORPTION is STRONGER than physisorption Explanation: Chemisorption is stronger than physisorption. Chemisorption involves the FORMING of a chemical bond between the ADSORBENT and the adsorbate whereas in physisorption, the molecules are held together by weak Van DER Waal’s forces. Therefore, chemisorption is stronger.
