To determine the standard state free energy change for a cell reaction determine the E o cell; determine the number of moles of electrons transfered in the reaction. WebAn electrolysis experiment is performed to determine the value of the Faraday constant (number of coulombs per mole of electrons). In this experiment, 28.8 g of gold is plated out from a AuCN solution by running an electrolytic cell for two hours with a current of 2.00 A. What is the experimental value obtained for the Faraday Constant?
