Question 5: Consider an interatomic potential function of the formA B12Er=76a) Find the equilibrium bond length, ro, as a function of A and B.b)Derive the bond energy as a function of A and B.c) You are given that ro= 0.1 nm and Erl=-5 eV. Calculate values for A and B (remember to keeptrack of your units).d) Take the second derivative of energy with respect to r and evaluate it at ro. This is effectively thespring constant of the bond. Look up spring constants of some typical metal and ceramic materialsonline. Where does your calculated value sit relative to these examples values?

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. For the molecule CO, the equilibrium distance between the carbon and oxygen atoms is 1.13×10−10m and the dissociation energy is 1.54×10−18J per molecule. Find the value of the constant a. Find the value of the constant b.
