• FugacityNarrower topic: Fugacity comparisons identify whether components can transfer between phases at equilibrium.

• State functionRelated: Equilibrium states provide the well-defined endpoints used to compare state-function values.

• Free energyRelated: At fixed constraints, equilibrium occurs at a minimum of the relevant free energy.

• State variableRelated: State variables have stable, well-defined values at equilibrium.

• Irreversible processCompared with: At equilibrium, no spontaneous irreversible change proceeds macroscopically.

• Molecular diffusionNarrower topic: Uniform chemical potential marks equilibrium after diffusion has removed its driving gradient.

• Dynamic equilibriumNarrower topic: Dynamic equilibrium describes ongoing balanced processes; thermodynamic equilibrium is the broader equilibrium framework.

• ExergyRelated: Equilibrium with the environment determines when exergy reaches zero.

• Helmholtz free energyRelated: At fixed temperature and volume, equilibrium minimizes Helmholtz free energy.

• Chemical activityRelated: Equal chemical potentials, and thus balanced activities, characterize equilibrium between phases.

• Law of mass actionRelated: Thermodynamics supplies the equilibrium constraints that modern mass-action expressions must satisfy.

• Standard stateRelated: Standard states are reference conventions, not claims that a substance is actually at equilibrium.

• Third law of thermodynamicsRelated: The entropy statement applies to equilibrium states of the crystal.

• Fourier's lawRelated: A temperature gradient marks departure from uniform thermal equilibrium and drives conduction.
