    I think I've done super bad in chemistry this year. 😒 Does anyone know when the resit would be? I'm definitely not gonna get the grade I want

    There'll probably be another paper in January, but it'll be changing to 9-1 exams soon, so not too sure

    i know right I found it hard too! Especially the last question - there I talked about more frequent and successful collisions, and also the fact that the ethyne gas expands in hot temperatures...that was a guess! I didn't want to say 'so less space so the particles collide more' because sometimes in qs like that if you put that you get 0/3...So hard!!
    Yes I put that and said it has higher surface area so more frequent successful collisions , I reckon the mark scheme for this q will be lenient and will except many answers, as it was never in our syllabus anyway

    Does anyone have any ideas about what topics the second paper would have?


    Posted from TSR Mobile
    I reckon the following topics have a chance to show up:
    .Haber & Contact process
    .Polymers
    .Electrolysis Calculations
    .Atomic Structures
    .Making of Ethanol

    I just know as much as someone who knows nothing. Just a rough idea

    yeah I think electrolysis will defiantly come up. Does stuff that was on paper 1 come up on paper 2?

    As far as I know, paper 2 consists of essentially all the topics from paper 1+ the more specialised stuff, some of which I just mentioned

    How did people include all those symbols for the galvanisation one?
    Wait what was that question?

    It is that a larger percentage of molecules have KE > than the Ea so there are more successful collisions.

    This is correct. A larger surface area of the solid would indeed increase the rate of reaction also. But the question specifically asked about increase of rate of reaction as temperature increased.

    I don't think I included all the symbols. Maybe about half of them. But I gave a good description of how galvanising works so hoping I only dropped a mark at most.
    I talked about iron being less reactive than zinc and included half equations for them creating ions and electrons. If the the iron can't create ions then it can't rust.

    'Using the symbols below, explain how a zinc coating prevents iron from rusting' or something like that

    I reckon around 75% (so 90 for this paper)

    Guys for the observations I said that the Grey Metal Magnecium dissapears. Do you know if I'll get a mark for that?

    Was it for the one put in gas of oxygen?
    Then you probably won't.
