Fugacity, f, is the product of partial pressure and fugacity coefficient.
From the en.wikipedia.org
The parameter is called fugacity, and it represents the ease of adding a new particle into the system.

Earth's mantle today has a relatively high oxygen fugacity, but in bodies like the Moon and early Mars, it is very low.

In the real world, for example, when making ammonia in industry, fugacity coefficients must be taken into account.

Magnetite reacts with oxygen to produce hematite, and the mineral pair forms a buffer that can control oxygen fugacity.

Native aluminium metal can be found as a minor phase in low oxygen fugacity environments, such as the interiors of certain volcanoes.
From the en.wikipedia.org
For reactions in the gas phase partial pressure is used in place of concentration and fugacity coefficient in place of activity coefficient.
From the en.wikipedia.org
To find out what how that lower oxygen fugacity affects carbon transfer, the researchers set up a series of experiments using volcanic basalt similar to those found on the Moon and Mars.
