Question
A chemist designs a galvanic cell that uses these two half-reactions: Write a balanced equation for the half-reaction that happens at the cathode. Cro¾¯(aq) + 4H₂O(1)+ 3e¯ Cr(OH)3(s)+5 OH (aq) Write a balanced equation for the half-reaction that happens at the anode. Answer the following questions about this cell. Write a balanced equation for the overall reaction that powers the cell. Be sure the reaction is spontaneous as written. Do you have enough Br₂(1)+2e information to calculate the cell voltage under standard conditions? П 0 half-reaction 0 Yes → 2 Br (aq) No standard reduction potential Eº 'red -0 E 'red = +1.065 V = -0.13 V ロ→ロ e X x10 5
