Copper is deposited at a cathode from solution with a bulk concentration of \(0.5 \mathrm{M}\) at the rate of \(3.0 \mathrm{~g} / \mathrm{m}^{2} \cdot \mathrm{s}\). Find the surface concentration of \(\mathrm{Cu}^{2+}\) at the cathode if the mass transfer coefficient from the bulk to the surface is \(1 \times 10^{-4} \mathrm{~m} / \mathrm{s}\).

Find the current density.

What will the maximum rate of deposition be?
