For Questions 13 14 A In a diatomic molecule potential energy of two atoms is approximately given by U r 612P where r is the interatomic spacing and A and B are positive constants Assuming the interatomic force to be conservative the corresponding force law is also called Lennard Jones Law It can be made out from the interatomic force law that atoms exert attractive forces on each other as the separation between them reduces The force law also tells that the force is repulsive at very short separations 14 13 Equilibrium distance between the two atoms in a diatomic molecule can be expressed as 1 6 B A D 28 B B 4A A 2B A B A B A B If the interatomic separation is equal to its equilibrium value what minimum energy must be given to the molecule in order to dissociate it C 1 6 B2 2A B 1 6 4B
