We’re being asked to determine the reaction that corresponds to the first ionization energy of rubidium and electron affinity of iodine.

Recall:

Ionization energy is the energy required to remove an electron from a gaseous atom or ion.

Electron affinity is the energy required to add 1 mole of electrons to a gaseous element. 


Given Reaction:      Rb(g) + I(g) → Rb+(g) + I-(g)
