An electrochemical reactor operates at standard state and 298 K. It consists of an electrode where silver is coated from a silver solution. The electrode area is 100 cm2. From kinetic measurements you know that the silver redox reaction has a symmetry factor of 0.5 and the exchange current density is 10 mA/cm2. The other electrode reaction is the formation of oxygen from hydroxide. The absolute operating voltage of the process is 0.8 V. Compared to the losses at the electrodes, all other losses can be neglected. It can also be assumed that the overpotentials of both electrodes have equal magnitude. Questions: a) Write down the half-cell reactions with the standard reduction potential and identify anode and cathode. b) What is the current in the electrochemical reactor?
