Resumen de Control of Chemical Equilibrium by Solvent: A Basis for Teaching Physical Chemistry of Solutions.
Oleg V. Prezhdo, Colleen F. Craig, Yuriy Fialkov, Victor V. Prezhdo
The mechanisms by which solvent can be used to control chemical equilibria are analyzed from a thermodynamic perspective and illustrated with several examples. The solvent effect is described in terms of universal- and specific-solvation components, and the practical and pedagogical means of separating these components are discussed. The exceptional ability to influence reaction yields simply by choice of solvent or composition of a solvent mixture is demonstrated with homo- and hetero-molecular association and conformational equilibrium. The material presented here provides an important addition to the physical chemistry curriculum that has been largely overlooked in traditional textbooks.
