Homework Statement
The interatomic force in the chlorine molecule Cl2 may be represented
by the Lennard-Jones potential:
with e = 1.79.10-19 J and r0 = 0.2 nm.
(i) Find the interatomic distance at which V(r) is minimized. What is the interatomic
force at this separation?
(ii) Calculate the potential energy at this separation.
(iii) Write down an approximate form for the potential at larger separations.
Comment (quantitatively) on how good this approximation is.
(iv) Make a simple estimate of the temperature required to cause Cl2 molecules to
dissociate.
(v) What is the frequency of vibration of the bond length?
