Question
(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 r0. This line runs from where to where?
from 2 to 5
from 4 to 2
from 1 to 2
from 2 to 3
from 4 to 5
from 1 to 3

total energy of a system is always constant.
at infinity PE=0 and at r0 PE= 1 to 3
total energy- PE = KE
thus KE= TE-PE = 0-(-PE) ie from 1 to 3
