(a) The diagram below is a graph of potential energy vs. interatomic separation for a particular diatomic molecule (that is, a molecule consisting of two atoms). For the energy level shown on the graph, imagine drawing a line whose length represents the kinetic energy when the interatomic separation is

. This line runs from where to where?

from 2 to 3 from 1 to 2 from 4 to 5 from 2 to 5 from 1 to 3 from 4 to 2
