Consider electrodeposition of copper on a copper electrode from an aqueous solution containing 0.5 × 10⁻³ mol⋅cm⁻³ CuSO₄.
Given: Faraday constant, F = 96500 Coulomb per gram equivalent.
Assume transport of reactant is rate limiting, and mass transfer coefficient is 10⁻⁴ cm⋅s⁻¹. The limiting current density (in mA⋅cm⁻²) is _______.
