Thermodynamic activity ( $a_{i} = exp [(μ_{i} - μ_{i}^{\circ}) / (RT)]$ )

Thermodynamic activity is a measure of the "effective concentration" of a species in a solution, taking into account interactions between particles. It provides a way to understand how the presence of other components in a mixture influences the behavior of a specific component compared to an ideal situation, where components behave independently. In ideal solutions, the activity ($a$) of a species is equal to its molar concentration ($C$).
