    Can you explain please.
    For pressure i wrote the rate of formation of propan 1 ol increases on increasing pressure.

    But then after that the question on temperature confused me

    To be honest that only made me.doubt my first answer.
    I wrote for the 3 marker- that the rate goes in the direction of the exothermic (only because the question said to me the reaction continues in forward direction being favoured more) so that was my explanation and it does this this to release the wnergy it was.given

    I think you're a but confused.
    For increasing pressure, the position of equilibrium moves to the side with fewer gaseous molecules. For increasing temperature, the position of equilibrium moves to the endothermic side.
    When increasing the temperature, the rate of reaction will increase (it has nothing to do with the reaction being eno/exothermic- the YIELD may decrease, but it wasn't asking about that for the 3 marker) because the particles have more kinetic energy so collide more frequently to overcome the activation energy.

    Thats nasty, our teacher hates the way the books teaches a lot of topics so he taught us other ways which are so much better. I'm coping with FP1 at the moment, just dont like alpha, beta, gamma roots etc much
    I just did a paper an did okay in it The book is okay, I've used examsolutions and mathsnet a lot though! Are you doing Edexcel too? Proof by Induction is horrible

    I did OCR FP1 last year, i wasn't a very good student last year and didn't revise, I failed futher maths (got a C), but i remember hating proof by induction it was the worst.

    Oh I'm on OCR, I quite like the proofs, they seem pretty constant, just follow the method and you're done. I don't like some of these consistant singular simultaneous equations though :/

    It's so boring, and there's so much you have to write

    They are like normal simultaneous equations like these:

    3x +6y =6
    6x +12y =12

    But they are obviously the same thing so they are 2 lines on each other, therefore the det is 0 and they have unlimited solutions blah blah, remember?

    I think i'm wrong about the 3 marker, because the 1 marker is the rate question (I think). The answer is that the rate will increase. Can you remember what the 3 marker was asking?

    No no.you are right. It.said.the rate of the forward.reaction increases. Explain why

    I treated the whole section with equilibrium! How stupid of me

    2 marks for stating and explaining what would happen to rate when temp increased, another 2 marks for pressure and I think 1 mark for stating what would happen to the yeild if temp went up.

    Wasn't there a question where we had to talk about the collision theory as well?

    The temperature and pressure questions were to do with equilibrium
