The root-mean-square (rms) speed of oxygen molecules `(O_(2))` at a certain absolute temperature is v.If the temperature is double and the oxygen gas dissociated into atomic oxygen, the rms speed would be

A

`v`

B

`sqrt2 v`

C

`2v`

D

`2 sqrt2 v`

Text Solution

Verified by Experts

The correct Answer is:
C
Apply `C = sqrt((3RT)/M)` , After dissociation a diatomic gas converts to monoatomic.
