The rms velocity of an ideal gas at 300 ...

The rms velocity of an ideal gas at 300 K is 12240 `ems^(-1)`, what is the most probable velocity at that temperature?

A

10000 `ems^(-1)`

B

11280 `ems^(-1)`

C

13250 `ems^(-1)`

D

12240 `ems^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
a
rms velocity of an ideal gas at 300 K is 12240 `cms^(-1)`
Most probable velocity, `C_(p) = 0.8166 xx` rms velocity
`= 0.8166 xx 12240``cong 10000 cms^(-1)`
