Electrochemical thermodynamics and kinetics - 4PMPTEL0

Goal(s)

Provide advanced notions in electrochemical thermodynamics and kinetics.

Content(s)

A - Thermodynamics

• AI - Electric, chemical and electrochemical potentials.
• AII - Thermodynamic equilibrium for homogeneous systemes and interfaces
• AIII - The galvanic chain: Nernst law, relationship between redox potentials and reaction thermodynamical parameters.

B - Current flow: non-equilibrium process

• BI - Mass balance: fluxes, current density (faradaic and capacitive), Faraday law.
• BII - Current flow through a volumic conductor: migration, convection, diffusion, macroscopic and microscopic aspects.
• BIII - Current flow through an interface : concentration profiles for a fast and reversible system, kinetic model of an heterogeneous reaction (E mechnism), steady-state polarisation for a fast (diffusion limitation: expression of the limiting current) or slow system (kinetic limitation: Butler-Volmer law).
