1 Ther­mo­dy­nam­ic Iden­tity 1/2 dU= TdS — PdV
2 Ther­mo­dy­nam­ic Iden­tity 2/2 dU= TdS — PdV +μdN
3 Gibbs’ and Helm­holtz’ Free Energy Energy avail­able for work under con­di­tions of con­stant pres­sure (Gibbs) or volume (Helm­holtz)
4 The Chem­ic­al Poten­tial μ
 The energy added to the sys­tem when you add a single particle
5 Gibbs’ and Helm­holtz Ther­mo­dy­nam­ic Identities Helm­holtz : dF= -SdT — PdV +μdN  and Gibbs : dG= -SdT + PdV +μdN
6 Free Energy and Equilibrium Max­im­ising the Entropy and minisim­ising the Gibbs’ and Helm­holtz’ Free Energies
