If the rms speed of the molecules of a gas at `27^(@)` C is 141.4 m/s , the rms speed at `327^(@)` C will be nearly _________ .

A

`1000ms^(-1)`

B

`922ms^(-1)`

C

`520ms^(-1)`

D

`849ms^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
B
`nu_(rms)=sqrt((3RT)/M),nu_(anu)=sqrt((8RT)/(piM))`
`nu_(anu)/nu_(rms)=sqrt(8/(3pi))=0.9216`
`nu_(anu)=0.9216xxnu_(rms)=921.6ms^(-1)`
