Differentiate and solve for the equilibrium bond radius r$0$ in terms of A$,$ B$,$ and n$.$

Experiments for a particular material show that the bonding energy is $5\mathrm{.}0$ eV for a bond length of $0\mathrm{.}33$ nm and n $=9\mathrm{.}0.$ What are A and B$?$

Sketch $($or better, use a spreadsheet to plot$)$ the attractive, repulsive, and total energy curves.

Calculate the thermal energy associated with temperature T $=1000$ K$.$ Assuming that the thermal energy can add to the bonding energy, sketch on your plot the region of energy that the system can access due to thermal excitation $($shade the area$).$

What are the expected minimum and maximum
