An electrochemical cell with a positive cell potential (E°) indicates a reaction that is:

A Nonspontaneous

B Spontaneous (ΔG < 0)

C At equilibrium

D Endothermic

✓ Correct Answer: Option B

ΔG = -nFE°. A positive E° gives negative ΔG, indicating a spontaneous reaction.

💡 Why is B) the correct answer?

The correct answer to the question "An electrochemical cell with a positive cell potential (E°) indicates a reaction that is:" is Option B: Spontaneous (ΔG < 0).

The other options — A) Nonspontaneous, C) At equilibrium, D) Endothermic — are incorrect for this MCAT Exam Prep question. As explained above: ΔG = -nFE°. A positive E° gives negative ΔG, indicating a spontaneous reaction.
