at 25 c Reduction Half-Reaction Cdng 13) Using Table 17.1, find Ee for 2 H2O() 2 H2(g) + O2(g). A)-1.23 V B)-0.40 V C) -0.80 V D)-206V 14)- 14) The cell reaction 2 Fe3-(aq) + Zn(s) Zn2.(aq) + 2 Fe2+(aq) occurs in the galvanic cell shown above. Where should the Fe3+(a) and Fe2+(ag) be found? A) Half-cell (A) contains Fe3+(n4) and Fe2+(a). B) Half-cell (A) contains Fe2+(ag) and half-cell (B) contains Fe3+(aa) C) Half-cell (A) contains Fe3+(ag) and half-cell (B) contains Fe2+(aq). D) Half-cell (B) contains Fe3 (ng) and Fe2 (a4)Explanation / Answer
Ans 13 : A) -1.23 V
The Eo for the cell is given as :
E cathode - E anode
= 0 - 1.23
= -1.23 V
