For the reaction: NaOH + HCI ➔ NaCl + H20 the change in enthalpy is called as _ ?
Correct answer: B. Enthalpy of neutralization
- A. Enthalpy of formation
- B. Enthalpy of neutralization
- C. Enthalpy of Sublimation
- D. Enthalpy of reaction
Explanation
In the reaction above an acid base reaction is taking place which is also known as neutralisation with hydrogen ion from the acid reacting with hydroxide ion from the base to form water.

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.
