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:

li(g)+f(g)→li+(g)+f−(g)

part a

what is the reaction that corresponds to the first ionization energy of lithium, li ?

part b

what is the reaction that corresponds to the electron affinity of fluorine, f ?

both a and b need to be in chemical equation.
