At 298 K, assuming ideal behaviour, the average kinetic energy of a deuterium molecule is

A

Two times that of a hydrogen molecule

B

Four times that of a hydrogen molecule

C

Half of that of a hydrogen molecule

D

Same as that of a hydrogen molecule

Text Solution

Verified by Experts

The correct Answer is:
D
`(KE)_("average") = 3/2 KT`
i.e., average kinetic energy depends only on temperature.
