Preferred Label : transfer activity coefficient;
Detailed label : transfer activity coefficient, γt;
IUPAC definition : A term used to quantify the difference in the free energy of a solute ion in two different
standard states often in two different liquid phases. The relationship is Δ t G
ν R T ln γ t where Δ t G is the transfer Gibbs energy and ν is the number of ions
in the solute.;
Scope note : it does not necessarily imply the physical transfer of a solute between two liquid
phases.; it should not be confused with the mass transfer coefficient which represents the
specific rate of transfer of a species from one phase to another.;
Origin ID : T06442;
