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

Explanation / Answer

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
