General Approach to Electrochemical Experiments Identify assumptions Ditusion- ass tran sort +Identify suitable boundary conditions Solye linear diffusion equation (Fick's 2nd law -use Laplace transtorm

Net flow of electrons from MNet flow of electrons from to solute solute to m .Ef more negative than Eredox more positive than Eredox more cathodic more anodic

Junction potentials Whenever we change electrolyte or solvent there is a cost in that we create a double layer (electrode)which has a small but often measureable potential We call this potential a junction potential

5 separate events must occur: -O must be successfully transported from bulk solution(mass transport) -O must adsorb transiently onto electrode surface (non-faradaic) CT must occur between electrode and (faradaic)
