Why are some solution processes exothermic whereas others are endothermic?

Text Solution

Verified by Experts

The correct Answer is:
The overall energy change associated with dissolution depends on the rolative magnitude of the solutesolute, solvent-solvent and solute-solvent interactions. The process is exothermic if the new interaction release more energy than disrupting the old interactions requires, it is endothermic if opoosite is true.
