Abstract:
Solvent effects on molecular solar thermal energy storage systems have been investigated using density functional theory combined with solvent models describing the effects of viscosities and dielectric constants on chemical reaction rates. We have addressed the following issues concerning how solvents influence both the thermochemical properties and the thermal relaxation kinetics of the studied systems, how the friction of the solvent influences the recrossing of the reactions along with the dynamics and force constants of the transition state. We observe that the rate constants for the chemical reactions of the molecular solar thermal energy storage systems depend strongly on the dielectric solvent properties and the viscosities of the solvents.

02:35Energetics of Solution Formation
When the strengths of the intermolecular forces of attraction between solute and solvent species in a solution are no different than those present in the separated components, the solution is formed with no accompanying energy change. Formation of the solution requires the solute–solute and solvent–solvent...

When ionic compounds dissolve in water, the ions in the solid separate and disperse uniformly throughout the solution because water molecules surround and solvate the ions, reducing the strong electrostatic forces between them. This process...
02:19Physical Properties Affecting Solubility
As for any solution, the solubility of a gas in a liquid is affected by the attractive intermolecular forces between solute and solvent species. Unlike solid and liquid solutes, however, there is no solute-solute intermolecular attraction to overcome when a gaseous solute dissolves in a liquid solvent since the atoms or molecules comprising a gas are far separated and experience negligible interactions. Consequently, solute-solvent interactions are the sole...
