Physical Chemistry | Theory of the van der Waals Gas Model

The video tutorial by Kevin Tokoph on Catalyst University explains the van der Waals equation of state, an extension of the hard shell model. It covers the equation's components, including the repulsive and attractive forces, and how these affect gas pressure. The tutorial also discusses the importance of constants 'a' and 'b', and how they are empirically determined. The video concludes with a comparison of van der Waals pressure to ideal gas pressure, emphasizing the balance between attractive and repulsive forces.

In what way does the van der Waals equation differ from the ideal gas law?

What happens to the pressure when attractive forces dominate over repulsive forces according to the van der Waals equation?

What is the role of the term 'b' in the van der Waals equation?
