    Thanks. Answer of pre-lab questions should b posted,too.. LOL

    Mr. Hayek,
    Thanks for this amazing video! I watched it before we did the lab at school. It was successful!!

    You are awesome my dude thanks.

    I have one question: What is the reason for using 6.00 ml of CV+ and 4.00 ml of NaOH? I know that changing the ratio would just change the rate of the reaction (make it faster or slower), and from my intuition I believe that it wouldn't change the "rate order". Please let me know if my train of thought is incorrect/correct.

      Yes you are right, changing the concentration will only change the reaction rate magnitude but the rate order would not change.

    Thanks Dr.Hayek they were very nice videos ^^

    I was not able to hear that well as to what you said about the absorption spectrum. If you could please clarify, that would be great.

      +Nathan Pavlovsky Could you please precise what time? Thanks.

    • @secnate
      @secnate 9 ปีที่แล้ว

      +Ali Hayek Starting at 9:57 and ending with 10:10 with the explanation of the wavelength of the absorptivity spectrum. It was difficult to hear sometimes and distinguish the words.
      Otherwise, great video! Thanks so much!

    • @AliHayek

      +Nathan Pavlovsky I am saying that we will not set the spectrophotometer to the maximum wavelength to not saturate the detector of the spectrophotometer; however, we will use a wavelength slightly on the shoulder of the spectrum so CV+ absorbs enough light and the detector does not get saturated with light.
      I hope this helps and thanks for your note.

    these were really nice!! but what are K'1 and K'2. How did we get those?

    • @AliHayek

      +addy hundito K'1 and K'2 are the pseudo rate orders.

    Amazing

    is it possible to determine the order of [NaOH] when only one trial was carried out?

    • @AliHayek
      @AliHayek  7 ปีที่แล้ว

      Elizabeth Moore you will need to measure the rate with two different [NaOH] to determine the order in NaOH. You can use excess of the other reactants.
