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 Determine ΔG°.

Question

Quizplus · Accepted Answer

The standard cell potential (E°cell) is calculated as E°cell = E°cathode - E°anode = 0.800 V - (-2.356 V) = 3.156 V. ΔG° is calculated using the formula ΔG° = -nFE°cell, where n is the number of moles of electrons transferred (2), F is Faraday's constant (96485 C/mol). ΔG° = -2 * 96485 * 3.156 = -609,000 J/mol = -609.0 kJ/mol.
