1. The problem statement, all variables and given/known data
Calculate the isothermal compressibility and the expansion coefficient of a van der Waals gas. Show, using Euler's chain relation that [tex]\kappa[/tex]_{T}R = [tex]\alpha[/tex](V_{m}  b). 2. Relevant equations van der Waals equation virial expansion of state 3. The attempt at a solution So I have to figure out isothermal compressibility of van der Waals gas expansion coeffcient of a van der Waals gas show that the above equation is true using Euler's chain relation. I guess the first part has something to do with compressibility factor Z? I used Z = PV/RT and then plugged for p the van der Waals gas law. Probabaly incorrect. The second and third part I have no idea.
