The Unit 5 notes have had a paragraph added to page 28, the final page, along with a few, much less profound, tiny tweaks to syntax. This was done following a discussion with Pam Kimber about the meaning of LO 5.18 – thanks, Pam!

The discussion has led to what I hope is a clarification and deepening of the notes in relation to that LO, but I am still a little concerned about the fact that the equation that describes the difference between Delta G and Delta G Standard, is missing form the new Equations and Constants sheet. However, for now, and until more exam evidence comes to light, I think the new tweaks are a pretty decent solution. Also, this post from a couple of years ago might be an additional, interesting read.
