GRAHAM'S LAW OF DIFFUSION

Graham Laws of Diffusion

Graham Laws of Diffusion

We know that gases which donot react chemically intermix irrespective of their nature. This is known as diffusion. The law of gravitation does not apply to diffusion which means that lighter gases can more downward while the heavier ones can move upwards. (i) State Graham's Law of diffusion. (ii)Give Its mathematical form. (iii) What is the value associated with the phenomenon of diffusion of gases?

Out of the three states of matter, only the gases have most of the physical properties common. They neither have definite shapes nor volumes. Upon mixing they form homogeneous mixture irrespective of their nature and can also be compressed on applying pressure. In addition to these, the gases obey different gas laws such as Boyle's Law, Charles's Law, Dalton's Law of partial pressures, Graham's Law of diffusion etc. Based upon these laws, ideal gas equation PV = nRT has been derived. Which pair of gaseous species diffuse through a small jet with the same rate of diffusion at same P and T ?
