Hey. Im currently studying chemical thermodynamics and have reached the section on solution thermodynamics.(adsbygoogle = window.adsbygoogle || []).push({});

For a pure liquid:

[tex]

\left(\frac{\partial g}{\partial P}\right)_T=RT \left(\frac{\partial ln(f)}{\partial P}\right)_T

[/tex]

Where g is the molar gibbs energy

P is pressure

T is temperature

R is the ideal gas constant

f is the fugacity

My first thought was to make use of one of the fundamental thermodynamic relations:

[tex]dg = v dP - s dT \Rightarrow \left(\frac{\partial g}{\partial P}\right)_T=v[/tex]

Where v is the molar volume and s is the molar entropy.

Anybody have any suggestions for a next step?

Thanks in advance,

Dan.
