Which of the following has maximum root mean square velocity at the same temperature ?

A

`SO_2`

B

`CO_2`

C

`O_2`

D

`H_2`

Text Solution

Verified by Experts

The correct Answer is:
D
`v_(rms) = sqrt((3RT)/(M)) therefore V_(rms) prop (1)/(sqrtM)` at same T because `H_2` has least molecular weight so its r.m.s velocity should be maximum.
