Vapour densities of O(2) and CH(4) are 3...

Vapour densities of `O_(2)` and `CH_(4)` are 32 and 16 respectivley. The ratio of rate of diffusion of `CH_(4)` to that of `O_(2)` is

A

`sqrt( 2) : 1 `

B

`1: sqrt( 2) `

C

`2: 1`

D

`1: 2`

Text Solution

Verified by Experts

The correct Answer is:
A
`( r ( CH_(4)))/( r( O_(2))) = sqrt((d ( O_(2)))/( d ( CH_(4)))) = sqrt(( 32 )/( 16)) = sqrt( 2) : 1 `
