Problem 5E

The following plot shows the potential energy of two Cl atoms as a function of the distance between them. (a) To what does an energy of zero correspond in this diagram? (b) According to the valence-bond model, why does the energy decrease as the Cl atoms move from a large separation to a smaller one? (c)What is the significance of the Cl¬Cl distance at the minimum point in the plot? (d) Why does the energy rise at Cl¬Cl distances less than that at the minimum point in the plot? (e) How can you estimate the bond strength of the Cl¬Cl bond from the plot? [Section 9.4]
