ΔH neutralization is always
Correct answer: B. -ive
- A. v
- B. -ive
- C. 0
- D. +ive or -ive
Explanation
ΔH neutralization refers to the enthalpy change associated with a neutralization reaction, which occurs when an acid reacts with a base to form water and a salt. In general, this reaction is exothermic, meaning it releases heat to the surroundings. As a result, ΔH (enthalpy change) for neutralization reactions is typically negative.

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.
