= Thermodynamic activity
{wiki=Thermodynamic_activity}
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\\)).
