Homework Statement
Show that the equation of state of an ideal gas with N molecules in a container of volume V at temperature T is P=NkT. Use the result derived earlier.
The result is A=-NkTlnZ, where Z is the partition function and A is the Helmholtz free energy.
Homework Equations
The Attempt at a Solution
P=-([tex]\delta[/tex]A)/([tex]\delta[/tex]V)T
P=NkT([tex]\delta[/tex]lnZ)/([tex]\delta[/tex]V)T
Here, I'm stuck. Surely, ([tex]\delta[/tex]lnZ)/([tex]\delta[/tex]V)T=0?
It seems so trivial. I don't understand what I'm missing. Thank you in advance.
