At constant volume and temperature conditions,the rate of diffusion $D_A$ and $D_B$ of gases $A$ and $B$ having densities $\rho_A$ and $\rho_B$ are related by the expression:
- A$D_A = D_B (\frac{\rho_A}{\rho_B})^{1/2}$
- B$D_A = D_B (\frac{\rho_B}{\rho_A})$
- C$D_A = D_B (\frac{\rho_A}{\rho_B})$
- D$D_A = D_B (\frac{\rho_B}{\rho_A})^{1/2}$
