    I don't think you understand the amount of lives you have saved and the amount of people who have gotten into their first choice uni just because of your video's. I always know if my teacher can't do it, Eliot Rintoul can! But honestly u deserve an award for taking your time to help us very confused kids

    Important to note at 18:25 that you can only cancel the x10 to the powers if the powers are all the same (eg in the example they are all to the power of -6 and thus you can just cancel them). great vid though helps explain it really clearly. :)

  • @yusufchristie1201

    I apologize in advance as this question may be badly worded . However, given a scenario when the concentration of one substance is halved and the effect this has is rate X4, but the other side of the table is not constant, how would we then work out the order of the other substance. Instead of multiplying by the initial rate by the orders square , would we then divide by the orders square?

    • @cabdulrahmanmohamed6884
      @cabdulrahmanmohamed6884 9 лет назад +3

      +yusuf christie nah...nvr divide...always times....but since u found a factor of (1/2) in the concentration of first molecule, work out the second one...
      if concentration change of the second molecule is 4; then order is 0 for first and 1 for second
      if concentration change of the second molecule is 2; then order is 0 for first and 2 for second
      if concentration change of the second molecule is 8; then ooder is 1for first and 1 for secoind
      etc etc etc
      so bascially Work out the concentration change of the second molecule......i see u saying the con for second is not constant....but u can still work out using the factor u got for molecule1 and some sort of info u'd be given in question or intial rates (or both)
      to conclude; never divide....just stick to multiplying (if wanna divide... multiply by 1/2)

    • @MrERintoul
      @MrERintoul  9 лет назад +1

      +yusuf christie I'm sorry that I missed your comment, but massive thanks to Cabdulrahman for helping! Right, so you're looking at a situation where in 2 experiments, each reactant has a different concentration i.e. no constants to make it easy. But you know that the rate is x4 when looking at the 2 experiments and that the first (which I will call A) is halved. In this case, you would need to know the order with respect to A. If it was 0 order, A would not affect the rate, 1 would mean that the rate would be halved and 2 would mean that the rate would be quartered (square of half). Once you know what A would have done to the rate, look at how the rate has changed from what A would have done to it and this tells you how the other reactant (which I will call B) has affected the rate based on the order. It's hard to go into too much detail without numbers really, but if you can find an example for me like this, I will try and help!

    In regards to the units of the K constant wouldn't it just be easier to remember that
    1 order - s^-1
    2 order - moldm^3s^-1
    3 order - mol^-2dm^6s^-1
    Instead of working it out like that, would save time.

    • @MrERintoul
      @MrERintoul  10 лет назад

      Imran Khan Hey, Imran!
      A good question! I can't say that I've seen a question like that (I may have missed it...) - but it's possible!
      Imagine the following rate equation...
      rate = k [A] [B]
      If you were asked to calculate the concentration of A, you would just rearrange the equation make [A] the subject.
      i.e. [A] = rate / ([B] x k)
      That helped?

    Hello Mr E Rintoul,
    First of all, thanks for helping me so much in AS, all I did for revision whilst on study leave was watch your videos and do past papers, and I think because of that both my unit 1 and 2 exams went really well, hoping for an A in August :)
    My question is, which topics in unit 4 and 5 are not covered yet?

Unit 5 is a little sparse still; there's electrode potential stuff to do, a load of stuff on complexes, entropy etc. The plan is to get it all done, it's just a slow process!

    Do you think you will be making any new videos soon? Could do with some help on the rest of chem4? :)
    Your videos are so helpful!

      rdhanda01 Honestly I can't remember which past paper the questions are from! Sorry! I can tell you that it would more than likely be from the start of the paper, but no more than that I'm afraid!

    @minesh5583 9 лет назад +1

    This was good, i watched this too see what a2 is about and not bad. If the
    rate eq = k[B]^2[C] Does the 2nd order act as a squared? Because when you calculated the value of k i see you did not take the 2 into acc but when calc the rate you did.

  • @gasIighter
    @gasIighter 4 года назад +1

    wait for 33:23 wouldnt E be 2nd order because the rate *changes* and you have to square 6 to get 36 then 36x0.26=9.36
