Use the given half reactions to "construct" an electrolytic cell.

Zn2+ + 2 e- → Zn Eocell=-0.76 V

Cu2+ + 2 e- → Cu Eocell=0.34 V

Predict the standard potential of the cell at 298 K.

2 What is the emf of a cell consisting of a Pb2+/Pb half cell and a Pt/H+/H2 half cell if [Pb2+] = 0.10 M, [H+] = 0.050 M and pH2 = 1.0 bar?

3 Calculate the Cu2+/Zn2+ ratio at which the following reaction is spontaneous at 298.15K Cu(s) + Zn2+(aq) Cu2+(aq) + Zn(s)

Calculate the standard potential of the cell consisting of the Zn/Zn2+ half-cell and the SHE. What will the emf of the cell be if:

[Zn2+]= 0.27 M

PH2 = 1.6 atm

[H+] = 1.8 M

E^ o =

E =

In depth explanation please! Also, is Ph2 included or not included in the Q expression? why? Also, sometimes I see the Q expression written as E^o=E-(.00592/2)ln(Q), but other times I see it as E^o=E-(.00257/n)(ln(Q). Is there a difference?
