Note that the IB sometimes refers to orders of reaction as partial orders of reaction. In this video, I use the term orders of reaction only.

Thanks alot for all of your videos.. They are really soo helpful and makes everything clear to understand

Can I just say a big thank you! Ive found your channel recently and you are godsent TT Youve helped me understand the content so fast and well and I truly appreciate all the effort you have put into producing such high quality content! Thank you :D

Glad I could help.

your videos are so helpful!! chemistry is hard and i thought i was going to fail my quiz because i understood nothing but i watched your videos and i got an 100% :)) if only there were other channels like this for biology and precalc

There is, I recommend using Alex lee for Bio. I take Bio Hl and I get decent grades just by using him

4:28 how do you know it has increased by factor of 16?

@MSJChem

Divide the initial rate of experiment 2 by that of experiment 1.

4:44 why is NO2 2nd order and not 4th order? When the concentration of NO2 increases by a factor of 4, the initial reaction rate increases by a factor of 16, so won't it be 4?

Second order means the rate increases to the square of the change. So a four times increase in concentration will cause a 16 times increase in the rate of reaction (four squared = 16).

Ah, ok. Thank you!

How do i know which experiments to compare?

Let’s say you have two reactants then you will compare experiments where the concentration of one is held constant and the other is changed. This allows you to see the effect of changing the concentration of one reactant on the rate of reaction.

@@MSJChem Thank you. I figured that out while solving the questions.

I love you

why isnt 2H2(g) having a superscript of 2

H2 is diatomic so it is written as H2. The '2' is front is a coefficient.
