- Homework Statement
- I'm trying to derive a thermodynamic relation in terms of P,V,T,Cp,Cv and was wondering if my working was correct. I am trying to derive (dG/dV) at constant temperature

- Relevant Equations
- dG= -SdT + VdP

dG= -SdT + VdP ... now dividing by dV holding temperature constant

(dG/dV)T = -S (dT/dV)T + V (dP/dV)T ... now dT and constant temperature cancel out

final answer:

(dG/dV)T = V (dP/dV)T

(dG/dV)T = -S (dT/dV)T + V (dP/dV)T ... now dT and constant temperature cancel out

final answer:

(dG/dV)T = V (dP/dV)T
