Question

Quizplus · Accepted Answer

The standard cell potential (E°) can be calculated using the standard reduction potentials for the half-reactions. Then, ΔG° can be calculated using the formula ΔG° = -nFE°, where n is the number of moles of electrons transferred and F is Faraday's constant. The correct calculation leads to ΔG° = -3.3 × 10² kJ.
