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

Quizplus · Accepted Answer

The reaction is spontaneous because the overall standard electrode potential (E°) for the reaction is positive. This is determined by calculating the difference between the reduction potential of silver ion (Ag+) and the oxidation potential of magnesium (Mg), which is the negative of its given reduction potential. The positive E° value indicates spontaneity.
