The ratio of the rate of diffusion of helium and methane under identical conditions of pressure and temperature will be

A

`4`

B

`2`

C

`1`

D

`0.5`

Text Solution

Verified by Experts

The correct Answer is:
B
`(r_(1))/(r_(2))=sqrt((M_(2))/(M_(1)))` (Graham's law of diffusion)
`(r_(He))/(r_(CH_(4)))=sqrt((M_(CH_(4)))/(M_(He)))=sqrt((16)/(4))=2`
