Question

Which of the following statements is true concerning the solution process?

Creating solvent cavities is exothermic, solute particles entering solvent cavities is endothermic

Breaking the intermolecular interactions in the solute is endothermic, creating solvent cavities is exothermic

Creating solvent cavities is endothermic, solute particles entering solvent cavities is endothermic

Breaking the intermolecular interactions in the solute is exothermic; solute particles entering solvent cavities is endothermic

Breaking the intermolecular interactions in the solute is exothermic; creating solvent cavities is endothermic

Breaking the intermolecular interactions in the solute is endothermic; solute particles entering solvent cavities is exothermic

Explanation / Answer

Typical steps in dissolution:

Step 1 --> Breaking solute-solute attractions (endothermic)

Step 2/3 --> Forming solvent-solute attractions (exothermic), in solvation.

therefore, best answer is the last one:

Breaking the intermolecular interactions in the solute is endothermic; solute particles entering solvent cavities is exothermic
