SUMMARY
The discussion centers on determining which cell reaction will yield more products at equilibrium based on their standard electrode potentials (E°). A positive E° value indicates a spontaneous reaction, while a negative E° value suggests non-spontaneity. The relationship between the equilibrium constant (K) and the E° value is established through the Nernst equation, which states that a higher E° correlates with a larger K, favoring product formation. Thus, the cell reaction with the positive E° will form more products at equilibrium.
