Activity Coefficients

Activity Coefficient is a dimensionless thermodynamic quantity that belongs to the class of partial molar properties, specifically representing the ratio of a component's effective activity to its mole fraction in a mixture, thereby quantifying deviations from ideal solution behavior in the context of solution thermodynamics.
