Problem: Classify each process as an endothermic or exothermic process.1. forming solute-solvent attractions2. breaking solute-solute attractions3. breaking solvent-solvent attractions

FREE Expert Solution

Exothermic reactions: lose energy and involve bonds forming; ΔH is negative

Endothermic reactions: gain energy and involve bonds breaking; ΔH is positive

1. forming solute-solvent attractions: bonds are being formed → exothermic.
