Gibbs free energy

  • thermodynamics Maxwell relation
  • Energy and Entropy 2020 The Gibbs free energy, \(G\), is given by \begin{align*} G = U + pV - TS. \end{align*}
    1. Find the total differential of \(G\). As always, show your work.
    2. Interpret the coefficients of the total differential \(dG\) in order to find a derivative expression for the entropy \(S\).
    3. From the total differential \(dG\), obtain a different thermodynamic derivative that is equal to \[ \left(\frac{\partial {S}}{\partial {p}}\right)_{T} \]
