Problem: Identify which redox reactions occur spontaneously in the forward direction.a. 2 Al (s) + 3 Pb2+ (aq) → 2 Al3+ (aq) + 3 Pb (s)b. 2 Ag+ (aq) + Ni (s) → 2 Ag (s) + Ni2+ (aq)c. Mg2+ (aq) + Zn (s) → Mg (s) + Zn2+ (aq)d. Sn (s) + Mn2+ (aq) → Sn2+ (aq) + Mn (s)

FREE Expert Solution

The higher the metal is in this table, the more active it is

The reactions at the top of the activity series of metals are most likely to occur in the forward direction

If we pair a half- reaction from the top of the list with the reverse of a half-reaction from the bottom of the list, we get a spontaneous reaction.

Problem Details

Identify which redox reactions occur spontaneously in the forward direction.

a. 2 Al (s) + 3 Pb2+ (aq) → 2 Al3+ (aq) + 3 Pb (s)

b. 2 Ag+ (aq) + Ni (s) → 2 Ag (s) + Ni2+ (aq)

c. Mg2+ (aq) + Zn (s) → Mg (s) + Zn2+ (aq)

d. Sn (s) + Mn2+ (aq) → Sn2+ (aq) + Mn (s)
