The study of heat changes that accompany a chemical reaction is called:
Correct answer: A. Thermochemistry
- A. Thermochemistry
- B. Electrochemistry
- C. Nuclear chemistry
- D. Chemical kinetics
Explanation
The study of heat changes that accompany a chemical reaction is called "Thermochemistry", therefore option A is the correct answer. Thermochemistry is a branch of physical chemistry that deals with the quantitative measurement of heat and energy changes in chemical reactions. It involves the study of heat transfer, enthalpy, entropy, and other thermodynamic properties of chemical systems.

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.
