The increasing order of effusion among the gases `H_(2), O_(2), NH_(3)` and `CO_(2)` is

A

`H_(2),CO_(2),NH_(3),O_(2)`

B

`H_(2),NH_(3),O_(2),CO_(2)`

C

`H_(2),O_(2),NH_(3),CO_(2)`

D

`CO_(2),O_(2),NH_(3),H_(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
Apply `r prop sqrt(1//M)`, Graham's law. The gas with lower molecular mass effuses faster
`CO_(2)(44) lt O_(2) (32) lt NH_(3) (17) lt H_(2) (2)`
