The rms velocity of CO gas molecules at ...

The rms velocity of CO gas molecules at `27^(@)C` is approximately 1000 m/s. for `N_(2)` molecules at 600 K the rms velocity approximately-

A

2000 m/s

B

1414 m/s

C

1000 m/s

D

1500 m/s

Text Solution

Verified by Experts

The correct Answer is:
B
`c_(rms)=sqrt((3RT)/(M))` so, `(c_(rms)(CO))/(c_(rms)(N_(2)))=sqrt((3RT_(300))/(M_(CO))xx(M_(N_(2)))/(3RT_(600)))`
or, `c_(rms)(N_(2))=1000xxsqrt(2)m//s=1414m//s`
