A vessel contains a mixture of one mole of oxygen and two moles of nitrogen at 300K. The ratio of the average rorational kinetic energy per `O_2` molecules to that per `N_2` molecules isA. `1:1`B. `1:2`C. `2:1`D. Depends upon momnets of inertia of two molecules . |
Answer» Both are diatomic gases and thus possess two degree of freedom associated with rotational kinetic energy. At same `T` they have same kinetic energy . | |
