Explain the physical significance of van der Waals parameters?
Answered by admin @
Hellooo
The van der Waals equation is an equation of state for a fluid composed of particles that have a non-zero volume and a pairwise attractive inter-particle force.
The equation is (p + n^a/v^2) ( v - nb) = nRT
Physical significance of ‘a’: ‘a’ is a measure of the magnitude of intermolecular attractive forces between the particles
Physical significance of ‘b’:
‘b’ is the volume excluded by a mole of particles.
