    This exam was solid, The rate of reaction question was harder than usual, the equilibrium question went down by a dodgy factor (1.7x10-3) I got , I found the ph to be the easiest which shows how hard the exam was, didn't get reactions for transition metals judging by posts, but surely you get the marks for the correct reaction. Last question I turned mass into moles that's about it so 1 or 2 / 7 , hopefully get 100ums or a little more / 150 :eek:

    Hi guys. This paper was an average one I thought.

    For the one where there was an increased concentration of H2-

    I think the concentration(or was it moles) of H2 will be more
    The concentration of I2 will be less
    and the conentration of HI will be more

    This is because it MINIMISES changes.

    For the question on iron and zinc, the first one was a redox, the 2nd was ligand subs.

    I didnt get the one where the ferrate ion was produced.

    Hey man how did u find it
    Don't think I got lower than 80, but I was AQA for AS-Level Chemistry so I didn't even know what Water of Crystalissation was, I don't think I lost too many marks on any questions before maybe maximum like 12 but that's pushing it.

    So assuming I just dropped 7 marks on the very last question think I'm still above 80.

    Facepalm.

    Oh well, did high enough for an A. Not sure about the A*, I will still try to get a high score on Chem 4 next week.

    Really pray those boundaries help me out.

    Meh, time to get some A*s in C3/C4 and Phys 5 and 4.

    Maths and Phys are no where near as confusing as Chemistry. You can pretty much derive everything from the Datasheet.
