A vessel contains a mixture of one mole of oxygen and two moles of nitrogen at 300K. The ratio of the average rotational kinetic energy per `O_2` molecules to that per `N_2` molecules is

Text Solution

Verified by Experts

The correct Answer is:
1
Both gases will have same number of rotational degree of freedom (equal to 2). Since both are diatomic and are at the same temperature. Average rotational kinetic energy per molecule for both the gases `= 2 ((1)/(2) KT)`.
Required ratio =1
