Calculate the exchange current density for a metal electrode immersed in a 1 M solution of its corresponding ions. The standard rate constant for the reaction is 6.3 x 10^-5 cm/s and the concentration of the electrons in the electrode is 5 x 10^23 atoms/cm^3. Additionally, assume the temperature is 25°C and the Faraday constant is 96,500 C/mol.
