Problem: For the dissolution of LiCl in water, Hsoln = -37 kJ/mol.Which term would you expect to be the largest negative number: Hsolvent, Hsolute, or Hmix?

🤓 Based on our data, we think this question is relevant for Professor Caldwell's class at UCONN.

FREE Expert Solution

ΔHsolution = ΔHsolute + ΔHsolvent + ΔHmix

Exothermic (-ΔHsolution) → ΔHmix > ΔHsolute + ΔHsolvent

Endothermic (+ΔHsolution) → ΔHmix < ΔHsolute + ΔHsolvent
