A chemist designs a galvanic cell that uses these two half-reactions: half-reaction standard reduction potential Cro (aq)+4 H₂O(+3e" ->>> Cr(OH)3(s)+ 5 OH (aq) red -0.13 V E red +1.065 V Br₂(1)+2e → 2 Br (aq) Answer the following questions about this cell. Write a balanced equation for the half-reaction that ☐ happens at the cathode. 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. ☐ Do you have enough Yes information to calculate the cell voltage under standard No conditions?
