Integrated Rate Law: First Order Reaction

Поделиться
HTML-код
  • Опубликовано: 10 фев 2025
  • A first order reaction has integrated rate law
    [A] = [A]0 e^(-kt)
    which is the same as ln [A] = -kt + ln [A]0
    Which means a graph of ln [A] vs time will give a line with slope -k and a y-intercept of ln [A]0.

      +Shaftell do you see how long this video is? 5 minutes is pretty long for something as trivial as integrating (which is btw math not chemistry) an expression. A professor at university cannot explain 1200 pages of literature in detail like this video is, in a given time of his class.

      came to think about it, that is the most selfish yet efficient way for universities to teach their undergraduate students, the mediocre will fall behind and the really smart ones will rise to the surface that way it automatically decides who to keep, all this while being lazy. Actually you will eventually need to learn by yourself at higher levels and if you can't figure out this kind of stuff on your own you are probably not meant for academics. When I go to university, I think ill get most of my tuition if the professor zeroes in on one of the class materials and walk me through his or her thought process from the basics to deeper things. WIth that way of thinking in my mind. I will try to do other parts on my own.

    to be precise: the rate of a reaction is directly proportional to the concentration of a reactant. The k is used merely to equate the two.

    Nate! I'm a biochemistry major and I love doing kinetics problems but I'm frustrated that I don't know how to go from a rate law to this y = mx + b form.... What do you suggest? I took calc in high school I'm just rusty as a nail. Thanks Nate!

    • @cesaralejandrojimenezmay4104
      @cesaralejandrojimenezmay4104 3 года назад +1

      It might be late but i will answer anyways. I recommend you to read the art of problem solving: introduction to algebra. It helped me a lot to understand the rate law in terms of y=mx + b. It doesn´t tell you the answer immediately but instead forces you to think. But don't worry if it seems hard for you, the book itself helps you by suggesting what steps you could take to solve a problem. The topic of interest (graph and lines) is the number 8 but you had better read it from topic 1 if you want to understand everything better because almost all lessons are intertwined to keep track the incoming knowledge. On the other hand, if you are struggling only with the calculus part, then only I can do is suggest to read any calculus book

    Its like a sight for sore eyes, I have the whole idea, but I am seeking how it would be realted to half life, though a plethoraof videos are outthere with (K=1/halflife). Since, most of the research articles employ first order rate to depict how the pollutant concentration over time, how it can be achieved when we have only final and initial concentrations, and change in time, and how to find K and half life?

  • @lejonbrames2101
    @lejonbrames2101 9 лет назад

    Thanks but I had one question which still confuses me. You did the indefinite integral first, but later added showed the definite integral by having an interval. On the left side, you integrated with respect to variable [A], but your interval is in terms of t. Shouldn't it be in terms of [A]? Sry, just learned integrals in calc 1 so it's still pretty new stuff

    • @RexGalilae
      @RexGalilae 9 лет назад

      You can take the definite integral of both sides from 0 to t. And that's what he meant to do. And it's ok if you want to write 0 to t in terms of A on the left hand side, rewriting the limits as A_initial and A_final.
      What matters is the time interval. On the right side, the time interval decides what value dt is going to take, whereas on the left side, this interval decides what's going to happen to [A].
      tbh, it's easier to explain when in person than when you're online. I agree that he didn't use the notations as strictly as its done in our math classes, which is what left you confused.

    • @RexGalilae
      @RexGalilae 9 лет назад
