According to Graham's Law, the rate of diffusion of CO , O ₂, ~N ₂ and CO ₂ follows the order:

Options

  1. ACO = N ₂> O ₂> CO ₂
  2. BCO = N ₂> CO ₂> O ₂
  3. CO ₂> CO = N ₂> CO ₂
  4. DCO ₂> O ₂> CO = N ₂

Correct answer

A. CO = N ₂> O ₂> CO ₂

Step-by-step solution

r 1 M Rate of diffusion decrease with increase in molecular weight Rate of diffusion order CO = N ₂> O ₂> CO ₂(28) (28) (32) (44)
