Transcribed Image Text:Part D
Suppose the distance between the two atoms is equal to the equilibrium
distance found in part A. What minimum energy must be added to the molecule
to dissociate it-that is, to separate the two atoms to an infinite distance apart?
This is called the dissociation energy of the molecule.
Express your answer in terms of the variables a and b.
