Exhibit 18-2 Consider a voltaic cell that is constructed from a strip of Ag dipped in an AgNO3 solution and a Fe (s) strip dipped in a solution of FeCl2 to answer the following question(s) . An external circuit and a salt bridge connect these two electrodes.
-Refer to Exhibit 18-2. Which cell reaction ensues spontaneously in this voltaic cell?
A) Fe2+ (aq) + 2 Ag (s) → Fe (s) + 2 Ag+ (aq)
B) Fe2+ (aq) + 2 Ag+ (aq) → Fe (s) + 2 Ag (s)
C) Fe (s) + 2 Ag (s) → Fe2+ (aq) + 2 Ag+ (aq)
D) Fe (s) + 2 Ag+ (aq) → Fe2+ (aq) + 2 Ag (s)
E) Fe2+ (aq) + Fe (s) → 2 Ag1+ (aq) + 2 Ag (s)
