The 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 concerned with the quantities of heat evolved or absorbed during chemical reactions.Endothermic and Exothermic reactions are the type of reactions that are characterized by whether the heat is evolved or absorbed during these processes. The heat of formation, also called standard heat of formation, enthalpy of formation, or standard enthalpy of formation, the amount of heat absorbed or evolved when one mole of a compound is formed from its constituent elements.

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.
