∆H per mole is expressed in the units of :
Correct answer: A. KJ
- A. KJ
- B. ∘F
- C. ∘C
- D. K
Explanation
The enthalpy change (ΔH) per mole is expressed in kilojoules per mole (kJ/mol).Kilojoules per mole (kJ/mol) are often used for convenience because the energies involved in chemical reactions can be relatively large.

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.
