In real gas equation, van der Waals constant (a) α forces of attraction.

1. α forces of attraction.
2. signifies intermolecular forces of attraction.
3. Higher is the value of ‘a’, easier will be the liquefaction of gas.
4. At high temperature and low pressure.

Correct answer: Higher is the value of ‘a’, easier will be the liquefaction of gas.

Solution

The van der Waals constant 'a' represents the magnitude of intermolecular forces of attraction. A higher value of 'a' indicates stronger intermolecular forces, making the gas easier to liquefy.
