At what temperature root mean sqaure of ...

At what temperature root mean sqaure of `N_(2)` gas is equal to that of propance gas at `STP` conditions.

A

`173.7^(@)C`

B

`173.7K`

C

`273 K`

D

`- 40^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
B
`v_(rms) (N_(2)) = v_(rms) (C_(3) H_(8))`
`sqrt((3RT)/(28)) = sqrt((3R 273)/(44))`
`T = 173.7 K`
