Explain how the magnitudes of the solute-solute, solvent-solvent, and solute-solvent interactions compared in order to account for the solution formation process being endothermic or exothermic

See explanation

Explanation:

Energy is absorbed by solute molecules as the solute-solute interactions are broken in order to make solute-solvent interactions as a solution is formed. The nature of solven-solvent interaction also determines the possibility of a solute-solvent interaction because like dissolves like. Polar substances can only dissolve in polar solvents and nonpolar substances only dissolve in nonpolar solvents.

Therefore, the solution formation process is exothermic if solute-solvent interaction is greater than solute-solute and solvent-solvent interaction.

Similarly, solution formation process is endothermic if the magnitude of solute-solvent interaction is less than the magnitudes of solute-solute and solvent-solvent interaction.
