Answer: After taking into account the adjustments for pressure and volume, the equation of van der Waals can be written as follows:
(P+an2/V2)(V-nb)=nRT
A and b are referred to as the van der Waals constants or parameters in this equation.
The importance of a and b can not be overstated in this context:
The value of ‘a’, independent of temperature and pressure, is a measure of the magnitude of attractive intermolecular forces within the gas.
And the volume that the molecule takes up is represented by the value of ‘b,’ while the total volume that all the molecules take up is represented by ‘nb.’
