High Quality Content by WIKIPEDIA articles! In chemistry, Solvent Effects is the group of effects that a solvent has on chemical reactivity. Solvents can have an effect on solubility, stability and reaction rates and choosing the appropriate solvent allows for thermodynamic and kinetic control over a chemical reaction.A solute dissolves in a solvent when it forms favorable interactions with the solvent. Dissolution depends upon the free energy change of both solute and solvent. The free energy of solvation is a combination of several factors.Firstly a cavity must be created in the solvent. The creation of the cavity will be entropically and enthalpically unfavorable as the ordered structure of the solvent increases and there are fewer solvent-solvent interactions. Secondly, the solute must separate out from the bulk solute.
