This lays out the mechanisms pretty well, although you should probably check the textbook as well just in case.

I'd look on chemsheets and then just draw them again and again until you can do them without looking at any answers or the actual mechanisms and then do some past paper questions. There's some good ones on physics and maths tutor which are really useful

Kc, Arrhenius, drawing graphs of Arrhenius and rate equations with rate determining steps maybe

Yeah Kinetics is always gonna come up on paper 2 though because it’s not supposed to come up on paper 1 (like , the spec says it’s only in paper 2)

Topics from paper 1 that could come up on paper 2 though;
Deffo kc they didn’t ask much of that at all. I think enthaply too? They didn’t ask any enthaply quetsions ! It was mostly thermodynamics rather than energetic

Compromise condition questions are usually badly answered and have appeared on AQA papers for the last couple of years as 6 mark questions. There was a compromise condition question on this year's AS paper 2. So maybe it's like the electrospray question that appeared this year on both AS and A2 paper 1.

Do you know where I can find practise 6 mark questions for compromise conditions?

Do you always have to include the partial charges when drawing mechanisms even if they haven't stated that you have to?

quick question about nmr (sorry if its a stupid one), what effects the chemical shift of the resonating 1H or 13C nucleas? is it how it feels the magnetic feild OR radio waves differently? (ik about electronegative atoms etc - just dont know if its to do with radio waves or magnetic feild). thanks!
