Let's evaluate each statement:
Statement I: "Easily liquefiable gases are readily adsorbed."
Gases that are easily liquefiable typically have higher critical temperatures, indicating stronger intermolecular forces.
These stronger forces favor adsorption onto surfaces, making such gases more likely to be adsorbed.
Statement II: "Adsorption enthalpy for physisorption is less compared to adsorption enthalpy for chemisorption."
Physisorption involves weak van der Waals forces and usually has an enthalpy change in the range of about 20−40kJ∕mol.
In contrast, chemisorption involves the formation of chemical bonds, leading to a much higher enthalpy change.
Since both statements accurately reflect the principles of adsorption:
The correct answer is Option A: Both Statement I and Statement II are correct.
