The van der Waals’ equation for a real gas is given by the formula are the pressure, volume, temperature and the number of moles of the gas. Which one is the correct interpretation for the parameter a?
View answer and explanation
Correct option: C
The parameter accounts for intermolecular interaction’s present in the molecule
Option C (The parameter accounts for intermolecular interaction’s present in the molecule) is correct because the 'a' parameter in the van der Waals equation accounts for the attractive intermolecular forces between gas molecules.
