Question

In van der Waals equation of state of the gas
law, the constant ‘b’ is a measure of
(a) volume occupied by the molecules
(b) intermolecular attraction
(c) intermolecular repulsions
(d) intermolecular collisions per unit volume

Answer 1

ANSWER

volume occupied by the molecules

SOLUTION

In van der Waals equation of state of the gas law, the constant  b is a measure of the volume occupied by the molecules. It gives the effective size of the gas molecules. The greater value of  b indicates a larger size of the molecules and smaller compressible volume.
