Equal moles of hydrogen and oxygen gases...

Equal moles of hydrogen and oxygen gases are placed in a container with a pin-hole through which both can escape. What fraction of the oxygen escapes in the time required for one-half of the hydrogen to escape-

A

`1/2`

B

`1/8`

C

`1/4`

D

`3/8`

Text Solution

Verified by Experts

The correct Answer is:
B
`(r_(O_(2)))/(r_(H_(2)))=sqrt((M_(H_(2)))/(M_(O_(2)))) or, (n_(O_(2))//t)/(0.5//t) or, n_(O_(2))=(1)/(8)`
