In this video, Mr. Krug reviews AP Chemistry Unit 9, which covers the Second Law of Thermodynamics and Electrochemistry. He includes a discussion of entropy and its calculations, thermodynamic favorability / spontaneous and nonspontaneous reactions, Gibbs Free Energy, kinetic control, as well as galvanic / voltaic cells, the Nernst Equation, and electrolysis calculations using Faraday's Law.
Note: At 1:34, there is a calculation error in the video. The correct entropy change should be +606.7 J/mol-K.
