what can i do without you.. thanks a bunch.
thank you so much for your good effort to making these notes supper learning material.!!!!
Thanks a lot for the Amazing Notes!
THANKS BEST NOTES I HAVE COME ACROSS IN A WHILE !!
Very impressive! Keep up the brilliant work!
These are lifesaving notes.
Nice and concise explanation very useful during examination revision
chemrevise is the wickedist ting
Thanks a lot for these notes
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.
You should follow the old one (module 1 and module 2). I am studying this under my chemistry teacher and they are good notes. Arranged.
It is fine to make a link to the website but not to download the files to be placed on another site.
This notes are so useful! keep posting notes like this!
best notes ever!!!!!!!!!!!!!!!!!!!!!! so grateful
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.
These are not written for the international A-levels but there will be overlap with them.
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.
I don’t think these notes completely match with international A-level, but if you are doing the exams this year the older syllabus is more relevant
Do you have any end of topics tests?, other than that, the notes are awesome, Thanks for sharing
no tests sorry although some etext book chapters have questions
Thank you so much!
Thanks for the valuable notes given. I am expecting to use them for my teaching purposes
I wish to make a donation you website saved my life
lol so true
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!
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”
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.
Got it, thanks!
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.
Good spot – will change
Thank you 🙂 …very useful

Top quality notes. You light up my life.
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
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!
I’m glad you like but I am now working on the new syllabus guides so won’t be uploading new resources for a while.
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.
Thanks. great to hear your students have found the notes useful
Thaaaank yoou soo much! 😀
Very helpful! thank you for making these notes 🙂
Thank youuuu. these made my revision much more easier
This notes are simply amazing. I am hoping to utilize them to the fullest of my abilities
Such a good website! Thanks loads 🙂
thank you so much for these amazing notes!! 🙂
