Discover LudwigThe phrase "activity coefficient" is correct and usable in written English.
It is typically used in scientific and technical contexts, particularly in chemistry and thermodynamics, to describe the effective concentration of a species in a mixture.
Example: "The activity coefficient of the solute was calculated to understand its behavior in the solution."
Alternatives: "effective concentration factor" or "reactive concentration coefficient".

This activity coefficient is designated by γ± to indicate that it is a mean activity coefficient for the positive and negative ions.
In most cases the activity coefficient, γi, is not equal to unity.
The activity coefficient of the solvent can, therefore, be found from total-pressure measurements, and, using the Gibbs-Duhem equation, it is then possible to calculate the activity coefficient of the electrolyte solute.
Activity coefficient, in chemistry, the ratio of the chemical activity of any substance to its molar concentration.
The activity is given by the product of the mole fraction xi and the activity coefficient γi.
The London theory indicates that for simple molecules positive deviations from Raoult's law may be expected (i.e., the activity coefficient γi is greater than 1, as explained previously).
Time-integrated activity coefficient.
cAverage time-integrated activity coefficient among male subjects (n = 3).
These data can be estimated using activity coefficient models.
Errors incurred when activity coefficient ratios are ignored are evaluated.
The activity coefficient and apparent standard potential have been obtained.
