摘要：
Enthalpic and entropic contributions to substituent effects on the ionization of meta- and para-nitrobenzoic acids in EtOH-H2O mixtures have been examined in terms of rho(H), sigma(H) and rho(s), sigma(s). The variations of rho(H) and rho(s) are attributed to the structural alteration of the mixed solvents. (C) 1998 Elsevier Science B.V.
