Calculate relative rate of effusion of O...

Calculate relative rate of effusion of `O_(2)` to `CH_(4)` from a container container containing `O_(2)` and `CH_(4)` in 3 :2 mass ratio.

A

`(3sqrt(2))/(4)`

B

`(3)/(4sqrt(2))`

C

`(3)/(2sqrt(2))`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
b
(b) `(r_(O_(2)))/(r_(CH_(4)))=(n_(O_(2)))/(n_(CH_(4))).sqrt((M_(CH_(4)))/(M_(O_(2))))`
`=(3)/(2)xx(16)/(32)xxsqrt((16)/(32))=(3)/(4sqrt(2))`
