activity

Activity (a) is a thermodynamic function used in place of concentration in equilibrium constants for reactions involving nonideal gases and solutions. For the species i activity is defined as a = f × c where ai is the activity of the species i, ci is its molar concentration, and fi is a dimensionless quantity called the activity coefficient.
