Preferred Label : additivity principle;
IUPAC definition : The hypothesis that each of several structural features of a molecular entity makes
a separate and additive contribution to a property of the substance concerned. More
specifically, it is the hypothesis that each of the several substituent groups in
a parent molecule makes a separate and additive contribution to the standard Gibbs
energy change (or Gibbs energy of activation) corresponding to a particular equilibrium
(or rate of reaction).;
