    on the partial fractions, the equation for partial pressures is wrong? Or have I missed something (partial pressure = mole fraction * TOTAL pressure?0

  2. i love chemrevise

    I’d just like to say thank you for making these revision guides. It has saved a lot of time in my revision and I like how it cuts straight to the point. It’s easy to read and understand.

    I am sitting the OCR AS-level exam this summer, and I’m a bit confused with the change of syllabus. Do I need to know all of Modules 2, 3 and 4? And how are they split across the two exams?

    Any help would be appreciated,

    Hi, I think there is a mistake on the 5.3.1 transition metal revision notes. On the example of the optical isomers the first example of the isomer has 2 less hydrogen since for 2 of the NH2 it is written NH instead. Please correct if I am wrong since I am lacking in knowledge of optical isomers (there isn’t much notes on that topic).

    Ps. I love your notes and I wouldn’t know what I would of done without them. They are really easy to understand and straight to the point. Thank you.

    Hi what would you recommend in terms of past papers or questions. Not sure if I should do the old ones or what really

  6. manesha

    hello sir.. this year I am sitting for June a level exam 2016 for the bnew syllabus I have some queries for the notes given it has solved my confusion in certain point in chemistry but in this revision notes apply for Cambridge international exam… I am in a confusion

    when will the revision notes for the new 2015 specification of OCR A chemistry be up. How different is the new OCR A specification compared to the old one. Thank you for producing these notes they are really helpful and i am able to grasp and understand things more better. all due to the fantastic notes you have produced.

      1. qwerty

        What differences are there specifically from the old and new spec? Also, are there many differences between ocr and AQA? Thanks, your revision guides are very good

        Hello, thank you sir for your help. Can you please send me the link for OCR A Chemistry starting from Sept 2015. thank you

    Hi thank you so much – extremely helpful!!
    Will you be doing notes for the new OCR September 2015 spec ?
    Thank you very very much :)))))

      1. MissChem

        Hi, I wanted to ask if the module 5 and 6 notes are complete for the new ocr a chemistry a-level spec. Also will you be adding the Arrhenius equation into the notes, relating to module 5?
        thank you soo much – Hope you have a grat year ahead!

    Hi, your notes are fab, thanks so much. However, for the f322 module 4, in the equation about ozone depletion, it says CLO.(dot for radical) + O.

    Surely only one of them can be a radical? Thanks again, you are amazing!!!

    1. chemrevise Post author

      I think I am right with the dots (in that all the substances written with them are radicals) but OCR don’t require you to write any dots with the equation.s.

    i want to donate some money perhaps. these notes are outstanding. i have done similar notes on OCR A which took me a year to make them because i was making sure to get all answers from mark scheme and then use them in my notes.

    1. chemrevise Post author

      No I have not done notes for the OCR B. A lot of the chemistry is similar to OCR A but the structure of the course is very different. There is some content unique to OCR B

    fantastic notes at last I found some very good notes for A-level chemistry….do recommend to any A- level student….
    Thanks a lot…
