The rms speed of oxygen molecules at a certain temperature is `upsilon`. If the temperature is doubled and the oxygen gas dissociates into atomic oxygen, the rms speed would be

`upsilon`

`3 upsilon`

`2 upsilon`

`2 sqrt(2) upsilon`

Text Solution

Verified by Experts

The correct Answer is:

When oxygen as dissociate into atomic oxygen M becomes half. As `upsilon_(rms) prop sqrt((T)/(M))`
`:.` when T is doubled and M is halved. `upsilon_(rms)` will becomes 2 times.
