Given below are two statements.
Statement-I: Easily liquefiable gases are readily adsorbedStatement-II: Adsorption enthalpy for physisorption is less compared to adsorption enthalpy for Chemisorption
The correct answer is
- A Both Statement-I and statement-II are correct
- B Both Statement-I and statement-II are not correct
- C Statement-I is correct but statement-II is not correct
- D Statement-I is not correct but statement-II is correct
Answer & Solution
Correct Answer
(A) Both Statement-I and statement-II are correct
Step-by-step Solution
Detailed explanation
(I) Easily liquefiable gases are adsorbed more easily because higher the critical temperature, higher is the intermolecular force of attraction and easier is the liquefaction. (II) Physical adsorption is an exothermic process but its enthalpy of adsorption is low…
