3. Edexcel Revision Guides

For all UK students you should now use the New A-level guides below.

At the bottom of the page I have left the old syllabus notes as I think they are more useful for the international  EDXCEL A-level Chemistry course. They were not written for the international course though.

New A-level 2015

The revision guides are in syllabus order. There are no modules.



3. redox



6. organic chemistry I

7. analysis

8. energetics I

9. reaction kinetics I

10. equilibria I

11. equilibria II

12. acid base equilibria

13. energetics II

14. redox

15. transition metals

16. reaction kinetics II

17. organic chemistry II

18. organic chemistry III

    I am from Bangladesh & the exam is of Edexcel syllabus. Should I follow the first content list ones OR the second content list(old syllabus) ones? And, will following one of this list cover everything from AS & A2 exam, as just a revision guide ofcourse?

    If possible, can you tell me what things should an A’level student, like me, do to get an A* probably?

    Thank you 🙂

      I didn’t write these guides for the international edexcel syllabus. It looks to me like the international follows fairly closely to old syllabus. The best thing for you to do is go through the syllabus and use the bits of the notes that are useful.

    hey I’m taking As exam on October this year , which notes is more suitable for me to study? Textbook? or AQA revisio guide? thanks!

    hi, great notes must say, although im confused.i’m sitting for the AS level International A level exams this year, so what syllabus is relevant to me: the old one or the new one? also if not relevant, where can i find something relevant if you had an idea.

      1. Haydenn

        Hi, what do you mean by it doesn’t match the international a level, does the content slightly different, as I have found some of the past international papers have some weird questions. Or is it just the style of questions that are different.?Thanks

        I wrote the edexcel guides looking at the UK syllabus. I have not looked at all at the international A-level so I really don’t know how useful they are.

    Im doing my IAL chemistry A2 exams on may, can u pleaze should i study from the old syllabus or the new one. I also have to tell that your notes really helped me get through the jan exams. Thank u soooo much for the notes.

    In 2-entropy.pdf, page 3 for the N2 + O2 ->2NO calculation (2nd box) for feasible temp, you have a couple of (possible) typos:

    1) “The reaction will be feasible when delta Stotal =0

    2) “delta S” = 25 J K-1 mol-1 – should this be “delta Ssystem” ?

    3) I’ve tried to derive the your value of 25 J K-1 mol-1 for delta Ssystem as follows:
    N2 + O2 -> 2NO
    S(N2) = 95.8 J K-1 mol-1
    S(O2) = 102.5 J K-1 mol-1
    S(NO) = 210.7 J K-1 mol-1
    ..giving delta Ssystem = 2(210.7) – (95.8+102.5) = 223.1 J K-1 mol-1
    which is x10 bigger than your value. Am I doing something wrong here?

    Using my figure for delta Ssystem I get a feasible temp of 809K – which makes sense to me in terms of possible temps attained in a car engine to produce NO pollution. Your value of T > 7200K seems super high!

    1. David

      some formatting has been stripped from post above so now doesn’t make much sense!

      Point 1 above in the PDF you have “reaction will be feasible when delta Stotal is *less than or equal* to 0” – should be “greater than or equal to”

    2. chemrevise Post author

      Yes the first two points are typo’s and I will update soon. Your 3rd point is not correct though. I had to look back to where I got the information from. It’s Jan 11 AQA module 5. The entropy values you are using for N2 and O2 are per atom of N and O so they need to be doubled. I found the values you are using in the Nuffield Data book and they are quoted per atom. 223 did seem a big number for a reaction of 2 moles of gas changing to 2 moles of gas.

    In the Group 2 notes: https://chemrevise.files.wordpress.com/2014/04/3-group-2-and-group-7.pdf

    bottom of page 2 you write: “The same effect will happen to a lesser extent with metals going up the group as the solubility decreases.” when explaining the effect of the sulphate produced coating the metal.

    I think it should read “…going up the group as solubility *increases*” – since the ‘coating effect’ would be less-and-less apparent as the sulphate ions would be dissolved going up the group.

    Thanks you soooooo much, i really needed amazing notes and now i found them
    Again thank you so much you must be a great person giving theses for free as well

  9. evie4learning

    Thank you so much for all these wonderful resources. Just a suggestion, I would be extremely grateful to have just a complied list of all the chemistry definitions specific to this exam board. I hope I don’t sound too greedy!

    You have made life so easy for a lot of people – young and old, teachers and pupils. I am in my 70,s and still teaching. I directed a pupil who was having difficulty to your website and he did so well he came and thanked me after he got his results. He thanked the wrong person. He should have thanked you.
    Most pupils don’t know how to revise and your concise notes help them. My current group of students whom I am tutoring are finding them very useful as well. If they do well you will get a big thank you from them. I will make sure of it.
