Which of the following pairs will effuse at the same rate through a porous plug .

A

`CO, NO_2`

B

`NO_2, CO_2`

C

`NH_3, PH_3`

D

`NO, C_2H_6`

Text Solution

Verified by Experts

The correct Answer is:
D
Because both NO and `C_2H_6` have same molecular weights `{M_(NO) = M_(C_2H_6) = 30]`
Rate of diffusion `prop (1)/(sqrt("molecular weight") )`
