The magnitude of heat of solution on addition of solvent to solution is:
Correct answer: A. decreases
- A. decreases
- B. remains constant
- C. increases
- D. None of the above
Explanation
Option A is correct because the solution temperature would decrease as there would be more substances absorbing the heat. The solvent will absorb heat in order to dissolve into the solvent.

About Thermochemistry and Energetics of Chemical Reactions
Thermochemistry measures energy changes in chemical reactions and distinguishes exothermic from endothermic processes. Work covers systems, surroundings and state functions, internal energy, the first law of thermodynamics, enthalpy and Hess's law, including the sign conventions used when heat enters or leaves a system.
