How Einstein condensation occurs? Consider a gas contained in a vessel with non-conducting walls. Let there be an electric field E applied across the gas by means of charged plates outside the vessel and n(x) be ions per unit volume at a distance x from the end of vessel. If the ions have a mobility µ, and D is the diffusion coefficient, determine the ratio of the diffusion coefficient to the mobility of ions.
