where K is the equilibrium constant and aX is the activity of X and described by the activity coefficient γX and [X]:. aX = γX[X]. W idth tt i ll t i. t l t.
Non-Ideality Through Fugacity and Activity
Fugacity is a direct measure of the chemical potential of a species in a mixture. • Fugacity coefficient of a pure gas or liquid: φpure gas(Tp) = f p.
THE LIQUID-LIQUID EQUILIBRIUM FOR ACTIVITY COEFFICIENT
The method has been appliedto the determination of activity coefficients of hydrocarbon binary systems using water as the solvent. Water is the ideal solvent
3. Activity Coefficients of Aqueous Species 3.1. Introduction
The Davies equation predicts a unit activity coefficient for all neutral solute species. This is known to be inaccurate. In general the activity coefficients
