Does anyone know if the interaction potential energy equation will be on the test? If so, what is an example of a problem where you would have to use it?

No calculations, but understand the concept, which is that greater distance will lead to a PE of 0 (no interaction), and greater polarizability of the two atoms will lead to a more negative PE (as there is a negative sign in front of the equation, and negative PE is favored).

Although calculations are not going to be tested, you should understand that Interaction potential energy is proportional to -(alpha1)*(alpha2)/(r^6)
where alpha is polarizability and r is the distance between the molecules.
