It has been shown in the preceding paper that for a given substance in a given state the fugacity is a definite property of which the numerical value can in most cases be readily determined, and which is well suited to serve as an exact measure ...

Oxygen fugacity is an equivalent of the partial pressure of oxygen in a particular environment (atmosphere, rocks, etc.) corrected for the nonideal character of the gas.

Fugacity is a thermodynamic property which is related to chemical equilibrium.
by Arkady N. Pilchin, Lev V. Eppelbaum
Oxygen fugacity is an important parameter in terrestrial systems, because it controls the content of FeO and Fe,O3, and also the stability of metallic iron. Higher oxygen fugacity means fewer iron silicates or fewer mafic minerals, because the ...

The principal advantage of introducing fugacity is that it enables all concentrations to be expressed in a single unit.

Fugacity is the thermodynamically driven escaping tendency of a chemical from a particular phase. It has units of pressure, and at low concentrations (such as usually occur in the environment) it is proportional to concentration. A difference in ...

Fugacity is an intensive property. It is a sort of idealized pressure. It has the same dimension as pressure, usually atm or bar. It is preferably used in the study of phase. It is also useful for multi-component equilibrium involving any combination ...

Fugacity is a very misunderstood principle but can be defined as the escaping tendency of a particular component within a system (Glasstone 1946). The fugacity ratio (f/p0) under normal temperature and pressure conditions can be replaced ...
