Which equation represents the change corresponding to the enthalpy change of atomisation of Iodine?
Correct answer: A. Option A
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
Enthalpy change of atomisation is when 1 mole of gaseous atom is formed from its element in their standard state under standard conditions. Only in this equation 1 mole of gaseous atom of Iodine is formed from solid diatomic iodine which is its standard state.

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.
