In a galvanic cell a spontaneous redox reaction occurs However the reactants are separated such that the transfer of electrons is forced to occur across a wire The resulting cell potential is measured in volts V and is defined by the equation given below E cell E red cathode E red anode A table of standard reduction potentials gives E values for common half reactions red Reduction half reaction E V 0 80 0 34 Ag aq eAg s Cu aq 2e Cu s Ni2 aq 2e Ni s Fe aq 2e Fe s Zn aq 2e Zn s 0 26 0 45 0 76 Part A Calculate the standard potential for the following galvanic cell which has the overall balanced equation Zn s Cu aq Zn aq Cu s Express your answer to three significant figures and include the appropriate units View Available Hint s E cell D S Zn s Zn aq Cu aq Cu s Templates Value Units
