A student wants to calculate the rate of an electrochemical reaction. They know that the concentration of the anodic reactant is 0.01 M and that the cathodic reactant is at a concentration of 0.02 M. The student also knows that the cell potential is 1.23 V, and that the Faraday's constant is 96485 C/mol. The reaction is:Fe(s) + Cu2+(aq) → Fe2+(aq) + Cu(s)What is the rate of the reaction in mol/s at standard conditions (25°C and 1 atm)?
