A `4 : 1` mixture of helium and methane contained in a vessel at 10 bar pressure. During a hole in the vessel, the gas mixture leaks out. The composition of the mixture effusing out initially is

A

`8 :1`

B

`8 : 3`

C

`4 : 1`

D

`1 : 1`

Text Solution

Verified by Experts

The correct Answer is:
A
`(R_(He))/(R_(CH_(4))) = (n_(He))/(n_(CH_(4))) sqrt((M_(CH_(4)))/(M_(He))) = (4)/(1) = sqrt((16)/(4)) = (8)/(1)`
