The amount of energy released when a million atoms of iodine are compl – InterviewSolution

1.	The amount of energy released when a million atoms of iodine are completely converted into I– ions in the vapour state according to the equation, I(g)+e–→I–(g) is 5.0×10–13 J. Calculate the electron gain enthalpy of iodine in terms of kJ mol–1.
Answer» The amount of energy released when a million atoms of iodine are completely converted into $I^{-}$ ions in the vapour state according to the equation, $I (g) + e^{-} \to I^{-} (g)$ is $5.0 \times 10^{- 13}$ J. Calculate the electron gain enthalpy of iodine in terms of $k J m o l^{- 1}$ .
