Predict the correct order of rate of diffusion of the following molecules.

Predict the correct order of rate of diffusion of the following molecules.
  1. SO2>SO3>PCl3>CO2
  2. PCl3>SO3>SO2>CO2
  3. CO2>SO2>SO3>PCl3
  4. CO2>SO2>PCl3>SO3

Solution

The diffusion rate of gases is inversely proportional to the square root of the molecular mass of the gases.

Rate ∝ 1M

The smaller value of M, the more rate of diffusion.
