11. The rate of diffusion is given by: 12. Diffusion control is rare in the gas phase, where rates of diffusion of molecules are generally very high. 13. However glutaraldehyde is a larger molecule, and so its rate of diffusion across membranes is slower than formaldehyde. 14. Therefore the rate of diffusion of different gases is inversely proportional to the square root of their mass densities. 15. This also means that the measured rate of diffusion will differ depending on the direction from which an observer is looking. 16. The rate of diffusion is given by ? c ? 2, with the rather favorable B " 2 scaling law. 17. In the sterilization system, the rate of diffusion toward the microbial sites increases as the gas concentration in the sterilizer is raised. 18. The parameter ? controls the rate of diffusion of the Brownian motion, and the behavior of SLE depends critically on its value. 19. The actual rates of diffusion and perfusion, and the solubility of gases in specific tissues are not generally known, and vary considerably. 20. The actual rates of diffusion and perfusion, and the solubility of gases in specific tissues is not generally known, and it varies considerably.
