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

Options

  1. ASO 2 > SO 3 > PCl 3 > CO 2
  2. BPCl 3 > SO 3 > SO 2 > CO 2
  3. CCO 2 > SO 2 > SO 3 > PCl 3
  4. DCO 2 > SO 2 > PCl 3 > SO 3

Correct answer

C. CO 2 > SO 2 > SO 3 > PCl 3

Step-by-step solution

The diffusion rate of gases is inversely proportional to the square root of the molecular mass of the gases. Rate ∝   1 M The smaller value of M , the more rate of diffusion.
