    Damn it, been on silver for a while. Tried making words out of all the letters but no success. Same with the units for each of the letters.

    The first one is close.
    Think about about charge equals.the letters 2-4 are wrong.everyhing else is right.

    (a^2n^2)/(bRTV^2)
    All the units except Pa cancel out, yet I can't seem to get the right answer..
    I believe you have the wrong equation.
    The equation you require is Van der Waals equation

    Are they all constants?
    No. Wait, are they to do with gas, energy, RTP, standard conditions? I'm just throwing words out now lol

    Seriously, the best thing to do is ignore the random beehive. If I ever get into Cambridge I'm going to ask Mr Keeler just how exactly that has anything at all to do with the question :/
    The beehive most likely represents a "spelling bee"

    Yeah. After dwelling over it for 6 months and losing a lot of sleep, we did eventually establish that

    No, they aren't constants and they are not the units either. It therefore cannot be C.

    Think about what each of them equals. You've already found these:

    (H-TS)=G
    -log(H+)=pH
    mc^2=E

    Q is assosciated with charge yes, but it's not supposed to be its' units. How do you calculate Q?

    Q=It


    N shouldn't even be in there, don't know where you've gotten that from. As for K, you've incorrectly re-arranged the Arrhenius Equation.

    Thanks for the help, although I am not sure if the entire response was directed at me; as I was wondering how the user got N also. I guessed that maybe they thought that since Na is avogadro's constant, the letter might be n to represent amount of substance

    Thanks again though - I'm going to have a look at the question again

    Does anyone know if there is a thread about the written Cambridge chemistry challenge for Y12?

    I have searched but can't find anything :/

    Thanks!

    Chemguide is great for a-level. Some of the more advanced stuff I usually try wikipedia.

    Thank you I know they are stretching AS knowledge but are there any specific areas or common topics they like to pick up on. I understand its not like normal past papers, but are there any specific areas I could look into in more detail.

    Nah. I did it last year (gold ) and you just need to know AS chemistry like the back of your hand.
