State
Standard free energy change relates to standard cell potential by ΔG° = −nFE°cell, where n is moles of electrons transferred and F is Faraday's constant.
Show
A reaction with a large positive E°cell yields a large negative ΔG°, the same verdict from two quantities.
Watch for
The electron count n must match the balanced overall reaction, not either half-reaction's unscaled count.
