In chemical thermodynamics, excess properties are properties of mixtures which quantify the non-ideal behavior of real mixtures. They are defined as the difference between the value of the property in a real mixture and the value that would exist in an ideal solution under the same conditions. The most frequently used excess properties are the excess volume, excess enthalpy, and excess chemical potential. The excess volume (VE), internal energy (UE), and enthalpy (HE) are identical to the corresponding mixing properties; that is,

has abstract	In chemical thermodynamics, excess properties are properties of mixtures which quantify the non-ideal behavior of real mixtures. They are defined as the difference between the value of the property in a real mixture and the value that would exist in an ideal solution under the same conditions. The most frequently used excess properties are the excess volume, excess enthalpy, and excess chemical potential. The excess volume (VE), internal energy (UE), and enthalpy (HE) are identical to the corresponding mixing properties; that is, These relationships hold because the volume, internal energy, and enthalpy changes of mixing are zero for an ideal solution.

(in) In termodinamica una grandezza in eccesso (in inglese excess property) è definita come la differenza tra i valori di una di una miscela in condizioni reali (o attuali) e in condizioni ideali (mantenendo costanti la pressione, la temperatura, e la composizione).In altre parole, le grandezze in eccesso esprimono le deviazioni di una miscela dall'idealità. Indicando con la grandezza di un componente nella miscela reale, la grandezza nella miscela ideale, e la grandezza in eccesso, sussiste la relazione: Così espressa, il valore di una grandezza in eccesso non è accessibile. Dobbiamo invece riferirci alla grandezza in eccesso parziale di un componente della miscela: In cui il soprassegno sta ad indicare che stiamo trattando grandezze parziali. La definizione di grandezza in eccesso è analoga a quella di grandezza residua, con la quale non va confusa. Alcune tra le grandezze in eccesso più utilizzate in ambito termodinamico sono il volume in eccesso, l'entropia in eccesso, l'entalpia in eccesso e l'energia libera di Gibbs in eccesso, definite dalle seguenti relazioni: La definizione di energia libera di Gibbs in eccesso è utile nella determinazione dei coefficienti di attività.
