    my calculus is so rough and this brought everything back for me. Thank you

    Professor Dirac once said, "I consider that I understand an equation when I can predict the properties of its solutions, without actually solving it." You have just helped me achieve this higher state of learning without spoonfeeding! Thank you from the bottom of my heart.

      Haha this is nice we just got done learning all the rules for deriving in AP calculus and I remembered that we had looked over derived and integrated rate laws in kinetics for AP Chem last year but it never really crossed my mind until then. This video has helped me grasp the concept of integrating, as you take the anti derivative and work in reverse which is pretty fascinating to me, of course I need to iron out the nuances to get a full picture of the various applied forms of calculus.

    Isn't this zero order

      This is first order. Note that, while one can define "half-life" for any system, it is only in a first order reaction that the half-life is independent of the initial value of reactant. Also note that for a zeroth order reaction, d[A] = k[A]⁰ = k.
