The van der waals forces are the greater in

If force of attraction between the molecules is negligible, van der Waals' equation (for one mole) will become:

The van der Waals constant ……………….. Measures the forces of attraction between the molecules of a gas.

For a non-zero value of force of attraction between the gas molecules and zero volume occupied by the gas molecules, give a modified expression of van der Waals' equation.

The term that corrects for the attractive forces present in a real gas in the van der Waal's equation is
