Multiple Choice
In a zinc-lead cell the reaction is:
Pb2+(aq) + Zn(s) → Pb(s) + Zn2+(aq) E° = 0.637 V
Which of the following statements about this cell is FALSE?
A) The zinc electrode is the cathode.
B) The reaction will go in the direction indicated.
C) The shorthand notation is Zn(s) ∣ Zn2+(aq) Pb2+(aq) ∣ Pb(s) .
D) The actual cell voltage is less than +0.637 volts because of concentration polarization and possible other factors.
E) The lead electrode is positively charged.
