Question

You MUST show your work to receive any credit. The quiz will be due at the beginning of class on 5/4/17. A cell is made of the following half reduction reactions: Cu^2+ (aq) rightarrow Cu(s) E degree = 0.34 V O_2(g) + 2H_2O(1) rightarrow 4 OH^- (aq) E degree = 0.40 V Write the balanced reaction. Write the description of the cell using cell notation. Assume the oxygen electrode uses Pt(s). Determine E degree_cell for the spontaneous reaction. Find the Delta G degree for this cell. Find K for this cell under standard conditions.

Explanation / Answer

1. The balanced equation is as follows:

Cu(s) + 4OH-(aq) = Cu2+(aq) + O2(g) +2H2O(l) + 4e-

2. The Cell notation will be:

Cu(s)|Cu2+(aq)||OH-(aq)|H2O(l)|O2(g)|Pt(s)
