SUMMARY
Substances with an endothermic heat of solution can dissolve due to the balance between enthalpy and entropy changes, as described by the Gibbs free energy equation (ΔG = ΔH - TΔS). The process requires activation energy to form activated complexes, which is influenced by temperature. Although the solution cools during dissolution, the increase in entropy (ΔS) can drive the process forward, making dissolution thermodynamically favorable under certain conditions.
