A vessel contains a mixture of one of oxygen and two moles of nitrogen at `300K` The ratio of the average rotational kinetic energy per `O_(2)` molecule to `N_(2)` molecule is .

`1:1`

`1:2`

`2:1`

`8:7`

Text Solution

Verified by Experts

The correct Answer is:

Both `O_(2)` and `N_(2)` are diatomic gases. Rotational degree of freedom in both cases is two. Therefore, average rotational kintic energy per molecule for each of then is `3(1/2kT)` or the ratio is 1:1.
