Consider an electrochemical cell containing a copper electrode in a 0.5 M CuSO4 solution and a silver electrode in a 1.0 M AgNO3 solution. Calculate the current density at a temperature of 25°C given that the copper electrode has a surface area of 5 cm² and the silver electrode has a surface area of 10 cm². The standard reduction potentials for Cu²⁺ and Ag⁺ are -0.34 V and 0.80 V, respectively. Use the Nernst equation to calculate the cell potential and then use Ohm's law to calculate the current density.
