0:00 Section 20.5 Free Energy and Equilibrium 2:05 Free Energy Calculation From Ecell Example 7:22 Example problems: Write balanced electrochemical equations, calculate Ecell standard and Delta G at 298K, and calculate the equilibrium constant. 23:51 Electrical Work Calculations 25:55 Converting Joules to kilowatt-hours 27:56 Example problem: Calculate the maximum electrical work that can be produced from an electrochemical reaction. These are the lectures that I use in my General Chemistry II course. The textbook I use is Brown, Theodore et al "Chemistry: The Central Science", Pearson, 14th Ed., 2018, ISBN13: 978-0134414232. Some images used in this video come from that textbook.
