A chemist designs a galvanic cell that uses these two half-reactions:

Half-reaction Standard reduction potential
O₂(g) + 4H⁺(aq) + 4e⁻ → 2H₂O(l) E⁰ red = +1.23 V
Fe³⁺(aq) + e⁻ → Fe²⁺(aq) E⁰ red = +0.771 V

(a) Write a balanced equation for the half-reaction that happens at the cathode.
(b) Write a balanced equation for the half-reaction that happens at the anode.
(c) Write a balanced equation for the overall reaction that powers the cell. Be sure the reaction is spontaneous as written.
(d) Do you have enough information to calculate the cell voltage under standard conditions?
