For each of the following reactions, a) separate the reaction into its component half reactions, b) write a schematic representation of the cell in which the reaction would occur in the direction written, c) calculate the standard potential of the cell, and d) assign the polarity of each electrode under conditions that the reaction would occur as written. A) Ag + Fe3+ = Ag+ + Fe2+.
B) VO2+ + V3+ = 2VO2+.
C) Ce4+ + Fe2+ = Ce3+ + Fe3+
