The plot below shows the potential energy of interaction between two atoms that can form
a diatomic molecule, as a function of their separation x. (The potential energy goes to zero
as x→ ∞o.) Assume that when the two atoms are bound together in a molecule, they sit
approximately at the minimum of the potential well. Is it possible for the bound system to
absorb a photon such that the molecule breaks apart and creates two atoms with equal
kinetic energy of 0.5 x 10-19 / when they are very far apart? Assume no changes in thermal
energy and no other interactions are present.

A. No, absorbing a photon of sufficient energy will produce atoms with a kinetic energy
that is smaller than stated in the problem.
B. No, absorbing a photon of sufficient energy will produce atoms with a kinetic energy
that is larger than stated in the problem.
CYes, the photon should have an energy of 2.5 × 10-1⁹J.
D. Yes, the photon should have an energy of 3.0 × 10-¹⁹J.
E. Yes, the photon should have an energy of 1.5 x 10-¹⁹J.
