    From the textbook:
    "A first order reaction can easily be identified from a concentration time graph. a first order reaction has a constant half life"


    The half lives were 190 then 210.

    Nowhere in the specification does it say "Half life is constant except sometimes when it's almost constant. It's still first order then."

    The half life was increasing. If the mark scheme only gives a mark for first order then that is ridiculous.
    these were EXPERIMENTAL RESULTS, which will always have experimental fluctuations. It was a constant half life

    Last two times it was ~60/100 raw marks for an A (120 UMS).
    Don't know how its gonna be this time, quite a few people thought it was good, quite a few thought it was horrible.
    most people thought it was terrible!! hoping its less than 50 for an A :| !!!

    You're a constant half life.

    Does any one have an answer for the Kc Calculation and the hydration of Mg2+
    I got Kc as 45
    And the hydration of Mg2+ as -2300 or something similar can't remember exact value

    i had this exact discussion with the people from my class after the exam. i hate to be all conspiracy theorist, but it seems a TINY bit odd that the year before uni fees skyrocket to £9000 per year all the exams are ridiculously difficult. compare F324 and F325 this year with 2010 and there's a huge difference in the difficulty of the papers.

    thanks OCR.
    I completley agree.
    And what makes me think this even more is, my friends who resat the AS June unit this year.... said that exam was as easy as anything?! So are they going to try and give the AS's a false sense of security and think they are awesome at the subject so they will go to uni and pay too much?? The exams will go dead easy next year you watch.
    i dont get it.

    For hydration it was -1941 or something like that did you multiply 2 by the hydration of Cl?

    And yeah I got that for Kc too.. quite weird to have an exact figure

    It was more complicated as it formed a solid precipitate so it didnt cancel
    I think I got that question wrong, in that I stated the precipitate was something which as far as I know if fairly soluble in water. Kind of disappointed there.

    I worked out three, and i got 190, 210 and 205. These are experimental fluctuations, and since the difference is well within 5% we can disregard them.

    I got the third half life value as 215. The way I was taught maths, 210 is greater than 190, and 215 is greater than 200 so I figured it was increasing.

    From the sounds of things though, the third value was closer to 200 than 210. I'm just venting at the amount of application marks, really.

    Worst exam ever, thought it was worse than the Jan 2011, and that was 65/100 for an A
    I'm hoping like 55/100 for an A this time, then there's a chance.. possibly haha
    couldn't do the buffer question or the last question and I forgot how to find pH from my Ka value so I messed that one up too =/

    I DID:

    (-( - LATT) + SOLUTION) - (HYD X 2) = HYD CL

    i dont think you had to double the Cl value? because it said blablabla IONS so i was assuming the value they gave us was for both the Cl why else did they say IONSSSSSSSSSSSSSSSS?????? either way i got a positive value lol but it looks like everyone here got a negative value!

    Did anyone get uses for H2 as hydrogen fuel cell vehicles and margarine production? Or does anyone know if they're right?
    Chances are they're fine. I wrote Haber and fuel cells
