We have to isolate the equations for ionization energy of potassium and electron affinity of bromine form this given equation.
K(g) + Br(g) → K+(g) + Br-(g)
Ionization energy is defined as the minimum energy required to remove a single valence electron from a gaseous atom.
Electron affinity is defined as the energy absorbed or released when a single electron is added to the valence shell of a gaseous atom.
The following reaction can be written as the sum of two reactions, one of which relates to ionization energy and one of which relates to electron affinity:
1. What is the reaction that corresponds to the first ionization energy of potassium, K?
2. What is the reaction that corresponds to the electron affinity of bromine, Br?
