In van der Waals' equation of state of the gas law the constnat 'b' is a measure of .

A

intermolecular repulsions

B

intermolecular attraction

C

volume occupied by the molecules

D

intermolecular collisions per unit volume

Text Solution

Verified by Experts

The correct Answer is:
C
Van der Waals' equation for one mole of a gas is
`(p+(a)/(V^(2)))(V-b)=RT`
Where, b is volume correction. It arises due to effective size of molecules.
