The atomic weight of C, N and O are 12, 14 and 16 respectively. Among the following pair of gases, which will diffuse at the same rate?
A.Carbon monoxide and carbon dioxide
B.Nitrous oxide and nitrogen peroxide
C.nitrous oxide and CO2✓ Correct
D.Nitrogen oxide and carbon monoxide
Explanation
From Graham’s law of diffusion 1 2 2 1 r M r M Molecular weight of nitrous oxide and CO2 is same, i.e., 44 g/mol. Therefore, they diffuse at same rate.
