The given apparatus is used to study the diffusion of a number of gases at the same temperature and pressure.

Which of the following pairs of gases would diffuse into the vacuum at the same speed ? [Given : Atomic mass of `H = 1` u, `C = 12` u, `N = 14` u, `S = 32` u, `O = 16` u]

A

`NH_3` and `H_2`

B

CO and `SO_2`

C

CO and `N_2`

D

` NH_3` and `N_2`

Text Solution

Verified by Experts

The correct Answer is:
C
Rate of diffusion depends upon the molecular mass of gases. `CO` and `N_2` have the same molecular mass hence, both will diffuse at the same rate.
