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