The study of measurement of heat absorbed or given out in a chemical reaction is referred to as:
Correct answer: C. Thermochemistry
- A. Endothermic reaction
- B. Exothermic reaction
- C. Thermochemistry
- D. Heat of formation
Explanation
Thermochemistry is the branch of chemistry that deals with the measurement and analysis of heat energy changes in chemical processes and physical transformations. It encompasses both exothermic and endothermic reactions, providing a broad framework for understanding heat changes.Endothermic reactions focus on heat absorption, while exothermic reactions focus on heat release, making them specific types of reactions within the broader scope of thermochemistry.The heat of formation is a specific thermochemical concept related to the formation of compounds from elements, but it doesn't cover the general measurement of heat in reactions.

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.
