The correct statement(s) about surface properties is (are)

Options:(select one or more)

Answer:

B, D

Solution:

Option B is correct: Adsorption is spontaneous, so $Δ G < 0$ . Since it's an exothermic process, $Δ H < 0$ . As randomness decreases, $Δ S < 0$ .

Option D is correct: Higher critical temperature implies easier liquefaction and stronger van der Waals forces, leading to greater adsorption. Ethane has a higher critical temperature than nitrogen.
