Multiple Choice
For the reaction: Mg(s) + AgNO3(aq) → Ag(s) + Mg(NO3) 2(aq) Ag+(aq) + e- → Ag(s) E° = 0.800 V
Mg2+(aq) + 2 e- → Mg(s) E° = -2.356 V
Is the reaction spontaneous and why?
A) No, Mg(s) does not react with Ag+.
B) No, E° is a positive value.
C) No, E° is a negative value.
D) Yes, E° is a positive value.
E) Yes, E° is a negative value.
