MCQ
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:

  • A
    Statement $I$ is false but Statement $II$ is true.
  • B
    Both Statement $I$ and Statement $II$ are false.
  • C
    Both Statement $I$ and Statement $II$ are true.
  • Statement $I$ is true but Statement $II$ is false.

Answer

Correct option: D.
Statement $I$ is true but Statement $II$ is false.
d
