🤓 Based on our data, we think this question is relevant for Professor Caldwell's class at UCONN.
ΔHsolution = ΔHsolute + ΔHsolvent + ΔHmix
Exothermic (-ΔHsolution) → ΔHmix > ΔHsolute + ΔHsolvent
Endothermic (+ΔHsolution) → ΔHmix < ΔHsolute + ΔHsolvent
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?
