At a certain temperature , the ratio of the rms velocity of `H_(2)` molecules to `O_(2)` molecule is

A

`1:1`

B

`1:4`

C

`4:1`

D

`16:1`

Text Solution

Verified by Experts

The correct Answer is:
C
As velocity `c=sqrt((3RT)/(M)), "so" (C_(H))/(C_(O))=sqrt((M_(O))/(M_(H)))=sqrt((16)/(1))=(4)/(1)`
