The amount of energy released when

10^6

atoms of iodine in vapour state is converted into

{I}^{-}

ion is

4.8 \times 10^{-13} \mathrm{~J}

. What is the electron affinity of iodine in

\mathrm{kJ} / \mathrm{mole}?

View answer and explanation

Correct option: B

289 \mathrm{~kJ}

Option B (289 kJ/mole) is correct because it accurately converts the energy released per atom to energy released per mole, which represents the electron affinity.
