Mass Transfer in Electrochemistry

This lecture covers the B-V model with mass transport, including charge transfer, electric double layer mechanisms, and various modes of mass transfer such as diffusion, migration, and convection. The Nernst Planck equation is used to describe mass transfer to an electrode, considering diffusion, migration, and convection. The lecture also discusses cases where migration or convection can be neglected, as well as the migration-limited case and mixed migration with diffusion. Linear diffusion approximations are explored, including cases where reactants are initially absent or present, and when the reactant is insoluble. The lecture concludes with a discussion on the transient response in the diffusion layer and potential step methods under diffusion control.
