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.
+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!
+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.
Thank you sir, this video explained everything so well. Definitely grateful to you and this video🙏
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.

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.

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