The concepts of non-Gibbsian and non-Lewisian properties in chemical thermodynamics
Literature Information
João Carlos R. Reis, Michael J. Blandamer, Michael I. Davis, Gérard Douhéret
The concepts of Gibbsian and non-Gibbsian, Lewisian and non-Lewisian thermodynamic variables are explored with respect to the thermodynamic properties of liquid mixtures and solutions. The general structures of equations for isochoric heat capacities, isentropic compressions and isentropic expansions are compared and contrasted. A simple rule is proposed for transcribing non-Gibbsian equations in terms of non-Lewisian partial molar properties. The bases of equations for partial molar isochoric heat capacities, isentropic compressions and isentropic expansions are examined for (i) components of liquid mixtures, and (ii) solute and solvent in solutions together with the properties of solutes at infinite dilution.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
