In van der Waals' equation of gaseous state, the constant ' b ' is a measure of
Options
- Avolume occupied by the molecules
- Bintermolecular repulsions
- Cintermolecular attraction
- Dpressure correction
Correct answer
A. volume occupied by the molecules
Step-by-step solution
van der Waals' equation for 1 mole of a real gas is (p+ a V^2 )(V-b)=R T where, b is volume correction. It arises due to effective size of molecules.
