Gibbs free energy

Summary

The Gibbs free energy ($G$) is defined as $G=F+PV$, where $F$ is the Helmholtz free energy, $P$ is pressure, and $V$ is volume. This is typically used for applications at constant pressure.

Details

This leads to $dG=-SdT+VdP+\mu dN$, where $S$ is entropy, $T$ is temperature, $V$ is volume, $P$ is pressure, $\mu$ is the chemical potential, and $N$ is the number of molecules (1).
