1 moles of an ideal gas are in equilibrium at fixed pressure (e.g. 106 Pa) and temperature (e.g. 300 K).
1)
What is the derivative of the gas' G with respect to volume for those conditions?
at fixed T,p,N dG/dV=
J/m3
2)
What is the equilibrium volume for those conditions?
V=
m3
3)
The two key features of an ideal gas are:
A) U depends only on N and T, not V.
B) The V dependence of S is given by a term Nk*ln(V)
For a gas that obeys (A) but has some excluded volume so S goes as , with b=1.1 × 10-28 m3, find the equilibrium volume V. All other conditions are the same as above.
Save the algebraic expression you obtain for V here because you may need it in another exercise later on.
