Energy changes in a chemical reaction can take place in the form of
Correct answer: D. all of these
- A. heat evolution
- B. heat absorption
- C. work done
- D. all of these
Explanation
Heat and work are two fundamental ways of energy transfer to and from the system.The energy changes in a chemical reaction can take place in the form of heat evolution, heat absorption, and work done.

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.
