• Grahams Law of Diffusion and Effusion

The process of effusion is quite different than the process of diffusion. The effusion is the process of forcing a gas through a pin hole from one compartment to another empty (vacuum) compartment. The Graham s law is also applicable to this situation. That means the above given equation are equally valid for effusion process also. 2

This equivalence is shown to be lost by the empirical equations of state in presence of an attractive nonideality. The modified forms are noted. We then construct a simple quantum mechanical model to simulate these results and obtain a one-to-one correspondence.

Graham s Law of Diffusion . When two gases are placed in contact they mix spontaneously. This is due to the movement of molecule of one gas into the other gas. This process of mixing of gases by random motion of the molecules is called as diffusion. In 1829 Graham formulated what is now known as Graham s law of diffusion. It states that
