Value of van der Waals constant ‘a’ signifies intermolecular forces of attraction. Higher is the value of ‘a’, easier will be the liquefaction of gas.

1. At high temperature and low pressure.
2. Higher the critical temperature more easily will the gas liquify.
3. Now since most easily liquefiable gas show larger deviation, NH3 will show maximum deviation from ideal behaviour.
4. Density = PM / RT = 5 × 28 / 0.0821 × 500 = 3.41g/mL.

Correct answer: Now since most easily liquefiable gas show larger deviation, NH3 will show maximum deviation from ideal behaviour.

Solution

Option C is correct because NH3 has strong intermolecular hydrogen bonding, leading to significant deviation from ideal gas behavior and easier liquefaction.
