Consider the electrolysis reactions cathode Cu?"(aq, 0.177 M) + 2e-= Cu(s) H,O) =0,(g, 1 bar) + 2H* (aq, 0.195 M) +2e- anode whose standard reduction potentials can be found in this table. Calculate the voltage needed to drive the net reaction if the current is negligible. Eçell = V The cell has a resistance of 66.0 Q and a current of 7.17 mA when the cathode overpotential is 0.231 V and the anode overpotential is 0.050 V. Calculate the voltage needed to overcome these effects and drive the net reaction. Eçell = V

Question
Consider the electrolysis reactions cathode Cu?*(aq, 0.177 M) + 2e-= Cu(s) H,O() =0,(g, 1 bar) + 2H* (aq, 0.195 M) + 2e- anode whose standard reduction potentials can be found in this table. Calculate the voltage needed to drive the net reaction if the current is negligible. Ecel = V The cell has a resistance of 66.0 Q and a current of 7.17 mA when the cathode overpotential is 0.231 V and the anode overpotential is 0.050 V. Calculate the voltage needed to overcome these effects and drive the net reaction. Ecell = V
