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.
