Thermodynamics deals with:
Correct answer: C. Heat of reaction
- A. Spontaneous reaction
- B. Rate of reaction
- C. Heat of reaction
- D. Entropy of reaction
Explanation
Thermodynamics deals with the energy changes during chemical processes, especially the heat of reaction, enthalpy, entropy, and equilibrium. It does not deal with the rate of reaction (chemical kinetics) or decide whether a reaction is spontaneous on its own; it requires a derived concept (that involves Gibbs free energy).

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.
