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)`

Verified by Experts

The correct Answer is:

D

`u = sqrt((3RT)/(M))` At constant `T, mu prop sqrt((1)/(M))`
Since `H_(2)` has the lowest molecular mass, `mu` will be maximum for `H_(2)`
