The Van der Waals Equation of State—C.E. Mungan, Spring 2000

The Van der Waals Equation of State—C.E. Mungan, Spring 2000 The ideal gas law is pRT υ= (1) where υ≡ Vn / is the molar volume. To obtain the van der Waals equation, we need to modify the pressure and volume.

This will make the expression for bij for spherical molecules to be bij = [(biil/3+ bjj1/3)/2 13 [I71 Then for non-spherical molecules expression for bij will be I \ With the use of these guidlines. we now derive the van der Waals mixing rules for the two representative equations of state.

Van Der Waals changed the molar volume to where b is related to the volume that one mole of these atoms or molecules occupy. The second change Van der Waals made to the ideal gas equation concerned attractive forces.
