The rms speed of oxygen molecules at a c...

The rms speed of oxygen molecules at a certain temperature `T` is `v`. If the temperature is doubled and oxygen gas dissociates into atomic oxygen, then the rms speed

Text Solution

Verified by Experts

`c=sqrt((3RT)/(M))=v`, `c'=sqrt((3R(2T))/(M//2))=2sqrt((3RT)/(M))`
`c'=2v`
