A chemist designs a galvanic cell that uses these two half-reactions: standard reduction potential half-reaction =-0.13 V Cro (aq)+4 H,0(1)+3e - Cr(OH),(s)+5 OH (aq) =+0.771 V E ed 2+ Fe (aq)+e Fe (aq) Answer the following questions about this cell. Write a balanced equation for the half-reaction that happens at the cathode. e Write a balanced equation for the half-reaction that happens at the anode. Write a balanced equation for the overall reaction that powers the cell. Be sure the reaction is spontaneous as written.
