Given below are two statements:

Statement I: In a diatomic molecule, the rotational energy at a given temperature obeys Maxwell's distribution.

Statement II : In a diatomic molecule, the rotational energy at a given temperature equals the translational kinetic energy for each molecule.

In the light of the above statements, choose the correct answer from the options given below:

Options:

Answer:
B
Solution:

The translational kinetic energy & rotational kinetic energy both obey Maxwell's distribution
independent of each other.
Translational kinetic energy of diatomic molecules=32kT
Rotational kinetic energy of diatomic molecules=22kT
So statement I is true but statement II is false.
