Question

Compare the rate of diffusion of carbon dioxide (CO2) & ozone (O3) at the same temperature.

Answer 1

Graham's Law of Effusion:

The rate of effusion of a gas is inversely proportional to the molar mass of the gas.

rate of gas 1 / rate of gas 2 = sqrt MW gas 2 / sqrt MW gas 1

Since we are only being asked to COMPARE the rates of CO₂ and O₃, we can just choose an arbitrary rate for O₃ as 1 and compare the rate of CO₂ to that.

rate of O₃ = 1

MW O₃ = 48

rate of CO₂ = x

MW CO₂ = 44

1/x = sqrt 44 / sqrt 48

1/x = 0.917

x = 1.09

So, this tells us that CO₂ will diffuse 1.09 times faster than O₃, or it will diffuse 9% faster
