In a diatomic molecule, the rotational energy at a given temperature

(a) obeys Maxwell’s distribution.

(b) have the same value for all molecules.

(a) Obeys Maxwell’s distribution.

(d) is (2/3)rd the translational kinetic energy for each molecule.

Comment : The equation <K.E. of translation> = (3/2)RT, <Rotational energy> = RT is taught. The fact that the distribution of the two is independent of each other is not emphasized. They are independently Maxwellian.
