Question

Derive expression for van der waals equation of state incorporating the parameters of a and



b. justify your answers

Answer 1

vander waals perameter a is that it is a major magnitude of the attractive forces among the molecules of the gas . higher is the value of A larger is the attractive forces . it does not depend on temperature and pressure .
the vander waals parameter b is that it is a measure of the effective size of the gas molecule and is equal to four times the actual volume of the molecules it is also called excluded volume or co volume.

Answer 2

The van der Waals constant 'a' represents the magnitude of intermolecular forces of attraction and the Van der Waals constant 'b' represents the effective size of the molecules.
