The reaction NaOH + HCl → NaCl + H₂O represents:
Correct answer: C. Enthalpy of neutralization
- A. Enthalpy of reaction
- B. Enthalpy of formation
- C. Enthalpy of neutralization
- D. Enthalpy of combustion
Explanation
This equation shows the reaction of a strong acid (HCl) with a strong base (NaOH) to produce a salt (NaCl) and water. The enthalpy change associated with this specific type of acidbase reaction is called the enthalpy of neutralization.

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.
