Question

State True or False.

All gases at the same $P$ and $T$ diffuses at the same rate.

• A. True
• B. False

Answer 1

The correct option is B False

Graham's law of diffusion states "under the same conditions of temperature and pressure, the rates of diffusion of different gases are inversely proportional to the square roots of their molecular masses or their densities."

Thus all gases at the same P and T do not diffuse at the same rate.
