Among the following which would have the highest rms speed 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
`c_(rms)=sqrt((3RT)/(M)) or, c_(rms)prop(1)/(sqrt(M))`
As `H_(2)` has the lowest molecular mass hence it has the highest `c_(rms)`.
