Question

Van der waals gas equation for n number of moles is given by the formula

Answer 1

To account for the volume that a real gas molecule takes up, the van der Waals equation replaces V in the ideal gas law with (V-b), where b is the volume per mole that is occupied by the molecules.

Answer 2

The formula for Van der waals Force is :

[P + a(n/V) ²][V-nb]=nRT
