Question 339: Thermodynamics & KTG

Question

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 :

Accepted Answer

The translational kinetic energy & rotational kinetic energy both obey Maxwell's distribution independent of each other.
T.K.E. of diatomic molecules = $${3 \over 2}kT$$
R.K.E. of diatomic molecules = $${2 \over 2}kT$$
So statement I is true but statement II is false.

Answer

Both Statement I and Statement II are true

Answer
