Quizplus · Accepted Answer

The cell reaction is spontaneous because the standard cell potential ($E^\circ$) is positive (0.34 V). The actual cell potential ($E$) can be calculated using the Nernst equation, which accounts for the non-standard conditions (concentrations not at 1 M). The slight difference from the standard potential suggests a small driving force for the reaction, indicating a positive but small cell potential, which aligns with choice B (0.418 mV).
