X ml of `H_2` gas effuses through a hole in a container in 5 sec. The time taken for the effusion of same volume of gas specified below under identical conditions is

A

10 sec : He

B

20 sec : `O_(2)`

C

25 sec : CO

D

55 sec : `CO_(2)`

Text Solution

Verified by Experts

The correct Answer is:
b
(b) `(r_(1))/(r_(2))=sqrt((M_(2))/(M_(1)))`
`(V_(1))/(t_(1))xx(t_(2))/(V_(2))=sqrt((M_(2))/(M_(1)))`
