Given van der Waals constants for NH3, H2, O2 and CO2 are respectively 4.17, 0.244, 1.36 and 3.59, which one of the following gases is most easily liquefied?

Question

Accepted Answer

NH3. The van der Waals constant 'a' is a measure of intermolecular forces. A higher 'a' value indicates stronger intermolecular forces, making the gas easier to liquefy. NH3 has the highest 'a' value (4.17), so it is most easily liquefied.
