Question:
In the van der Waal's equation, 'a' signifies:
intermolecular attraction
intramolecular attraction
volume of molecules
attraction between molecules and wall of container
Solution:
The van der Waal's equation corrects the volume and attractive forces between the gas molecules. The magnitude of 'a' is indicative of the strength of the intermolecular attraction. So the constant ' a ' provides the correction of intermolecular forces. Option A is correct.
