Assetion: Carbon dioxide has greater value of root mean square velocity `mu_(rms)` than carbon monoxide.
Reason: `mu_(rms)` is inversely proportional to molar mass.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
D
`mu_(rms)=sqrt((3RT)/(M))` is inversely related to molecular mass.
Therefore, `mu_(rms) (CO)gt mu_((rms))(CO)_(2)`.
