    Anyone prepared to guess grade boundaries? 92 cap? Or too low?
    I think 90 cap, possibly slightly lower.

    Last year's paper (which had a 92 cap) was significantly easier than this.

    Guys - I need an A* but I think I have dropped 15-20 marks? No hope!
    There is always hope.
    AQA set a ridiculous exam, and our group is dedicated, led by myself, to forming an already outstanding argument to AQA and making a petition, we are a FB group and will start the petition in the next few days. Our numbers our nearing 1000 and I only started it at round 6:30pm.
    A lot of people think this is unfair and they are right for reasons shown on the group.
    Here is the link, join us, spread this link far and wide, share it on all social media and with family and friends and school and classmates, get as many people as you can to join then we can get some justice.

    https://www.facebook.com/groups/148389988911787

    I know we all have exams, just join us, share us and pop back in every few hours to see updates and when we'll be ready to petition.

    [QUOTE=Cadherin;65786359]I think 112 and 114 will be allowed, as the probability of 35 : 35 is equal to that of 35 : 37
    Well thats one more mark gone.

    Yeah it's from June 14 exam
    When Silver Fluoride dissolves in water at 25 degrees, the free energy change is -9 kJ mol-1. Use this info and data from table 2 to calculate a value with units for the entropy change when silver fluoride dissolves in water at 25 degrees.

    so ∆G = -9
    ∆H = -15
    T = 298

    How do I rearrange it to get ∆S on the left hand side is what I'm asking and is there a certain way of doing it because I have no idea haha
    This is a bit late (sorry for that!) But here's how I would do it.

    Ok, so you know delta G, enthalpy and the temperature so using the origional equation, just plug the values in.

    so,

    -9=-15-((delta S)*298)

    1. Bring the -15 over to the other side (ie add 15 to both sides)

    6=-298S

    2.divide 6 by -298

    S= -0.02

    3.Convert this into the correct units

    = 20.13JK^-1Mol^-1


    Does that make sense??

    Do you think you can put NaOH with an acid catalyst for the hydrolysis of the Estee???Also does anyone remember the moles we were given when we had to work out KC that got an answer of 9.09x10-3 I know one was 0.58 another was 3.76 I think???? What were the other two?

    Was a tough paper, but I can't see the AQA doing much - the questions about lidocaine/polymers for stitches etc were how science works questions that required thinking outside of the box, they've been pretty on point with the HSW stuff in the past couple of years.

    That's not to say that the AQA don't realise when they've went off the beaten track - a similar thing happened with the controversial June 2012 CHEM5 paper, there was an outrage including newspaper coverage on it and the AQA lowered the grade boundaries considerably (79 for A* and 71 for an A).

    surely they have to do something since thousands of people are complaining? The reaction to this exam is not the usual reaction therefore they did something wrong...

    Currently revising Chem5 after that atrocious chem4

    How much do we need to know about reversible and irreversible cells? Do we need to know the half equations for examples etc or do we only have to know that the reaction can be reversed in rechargeable cells?
