Given:Ag+(aq) + e- → Ag(s)E° = +0.799 VAgI(s) + e- → Ag(s) + I-(aq)E° = -0.152 VNi2+(aq) + 2 e- → Ni

Given:   Ag+(aq) + e- → Ag(s)   E° = +0.799 V
   AgI(s) + e- → Ag(s) + I-(aq)   E° = -0.152 V
   Ni2+(aq) + 2 e- → Ni(s)   E° = -0.267 V

Which of the following reactions should be spontaneous under standard conditions?

   I.   2 AgI(s) + Ni(s) → 2 Ag(s) + 2 I-(aq) + Ni2+(aq)
   II.   Ag+(aq) + I-(aq) → AgI(s)

A) I and II are both nonspontaneous.
B) I is nonspontaneous and II is spontaneous.
C) I is spontaneous and II is nonspontaneous.
D) I and II are both spontaneous.
