thermodynamic activity

The fugacity is closely related to the thermodynamic activity.

An equivalent statement uses thermodynamic activity instead of fugacity.

The partial pressure of a gas is a measure of thermodynamic activity of the gas's molecules.

Dissolving electrolytes reduces thermodynamic activity (aw), vapour pressure and autoprotolysis of water.

However, of fundamental importance is the carrier (micellary or lamellary) in which these compounds are inserted and which influences their thermodynamic activity and the consequent interaction with skin.

The first equilibrium to the right and the second to the left, meaning that HF is extensively dissociated, but that the tight ion pairs reduce the thermodynamic activity coefficient of HO, so that the solution is effectively less acidic.

It was there that he and Debye developed their theory (the Debye-Hückel theory, in 1923) of electrolytic solutions, elucidating the behavior of strong electrolytes by considering interionic forces, in order to account for their electrical conductivity and their thermodynamic activity coefficients.
