There have been quite a number of changes to the UNIT 03 notes, many of which are cosmetic, but one of which is certainly not.

The College Board policy of randomly deciding that Le Chatelier arguments are no longer acceptable for discussions surrounding predicting the voltage in non-standard cells, coupled with their rejection of the Nernst equation in the new curriculum, has forced me into re-thinking explanations surrounding non-standard conditions and voltages in electrochemistry. The folly of Big Ideas also plays into the issue by separating electrochemistry from equilibrium, but I have resolved it to my satisfaction by tweaking the idea of how I use the term driving force, in particular on pages 35 and 36 of the revised notes.
