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?

Question

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?

Quizplus · Accepted Answer

The reaction is spontaneous because the overall cell potential is positive (0.800 V - (-2.356 V) = 3.156 V), indicating that the reaction will proceed spontaneously in the direction written.
