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

Options

A. obeys Maxwell's distribution
B. have the same value for all molecules
C. equals the translational kinetic energy for each molecule
D. is `(2//3)` rd the translational kinetic energy for each molecule

Explanation

To solve the problem regarding the rotational energy of a diatomic molecule at a given temperature, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Degrees of Freedom**:
- A diatomic molecule has translational and rotational degrees of freedom.
- For translational motion, a diatomic molecule has 3 degrees of freedom (movement along x, y, and z axes).
- For rotational motion, it has 2 degrees of freedom (rotation about two perpendicular axes perpendicular to the bond axis).
