{wiki=Exchange_current_density}
Exchange current density, often denoted as \\( j_0 \\), is a crucial parameter in electrochemical kinetics and interfaces, particularly in the context of electrochemical reactions. It represents the current density at which the rate of the forward reaction (e.g., oxidation) is equal to the rate of the reverse reaction (e.g., reduction) in a system at equilibrium.
