This study guide covers thermodynamically favorable and unfavorable reactions, including spontaneity based on ΔG° and K. It explains how electrolytic cells drive nonspontaneous reactions with electricity. It also details coupled reactions, using a spontaneous reaction to drive a nonspontaneous one via a common intermediate, with examples and calculations using Hess's Law. Finally, it provides practice problems and exam tips focusing on these concepts.
