For each monomer being integrated in a complex of degree n, its contribution
to the enthalpy departure is �hin / n or �hMij / 2, respectively. Hence, �ha can
easily be derived by

Isothermal entropy and Gibbs energy departure:
A similar expression for �ga should hold as it does for the enthalpy departure
(eq. 20):
