What is the value of enthalpy of neutralization when one mole of strong base reacts with one mole of strong acid?
Correct answer: D. -57.4KJ/mol
- A. -60.5 KJ/mol
- B. -46.5 KJ/mol
- C. -70.5 KJ/mol
- D. -57.4KJ/mol
Explanation
The enthalpy of neutralization when one mole of strong base reacts with one mole of strong acid is approximately -57.1 kJ/mol. This means that 57.1 kJ of heat is released when one mole of strong base reacts with one mole of strong acid.

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.
