Homework Statement
Calculate the Gibbs free energy for a van der Waals gas (up to an integration constant), assuming a fixed amount of material and temperature.
Homework Equations
[tex]P = \frac{NkT}{V-Nb} - \frac{aN^2}{V^2}[/tex]
dG = -SdT + VdP + udN (where u is the chemical potential)
The Attempt at a Solution
I am unsure of where to begin. I've tried looking at supplementary materials but everyone says stuff like "finding other free energies leads to 3rd order polynomials". If anyone can start me off I'd be grateful! Thanks!:!)
