Entropy–enthalpy compensation as a fundamental concept and analysis tool for systematical experimental data

Abstract

Enthalpy-entropy compensation (EEC) has a definite physical sense. Here, we review EEC from a new standpoint, using the notion of correlation. The latter has two basic meanings: (a) 'A' is correlated to 'B' means 'A' results from 'B' or vice versa; (b) this same means there is some real, but hidden 'C' in connection to both 'A' and 'B'). In accordance with the interpretation (b), we try rationalizing EEC in terms of hidden, but physically real factors. © 2012 Elsevier B.V. All rights reserved.
