Select the true statement about the energetics of solution formation.

A. The disruption of solute-solute attraction is exothermic.
B. Dissolution of a solute can occur only if the overall process, [tex]\Delta H_{sol}[/tex], is endothermic.
C. The disruption of solvent-solvent interactions is exothermic.
D. The formation of solvent-solvent interactions is exothermic.
E. Dissolution of a solute can occur only if the overall process, [tex]\Delta H_{sol}[/tex], is exothermic.



Answer :

GinnyAnswer

Final answer:

The formation of solvent-solvent interactions is exothermic.


Explanation:

The true statement about the energetics of solution formation is:

  • Option D: The formation of solvent-solvent interactions is exothermic.

When a solution is formed, energy is released in the step where solute-solvent interactions are established. This is an exothermic process that results in a negative overall enthalpy change, indicating an exothermic solution formation.
