hi! I am dyscauculic with ADHD and I've been for like, 3 years without understanding chemistry trying my hardest, usually I don't watch youtube classes cause they don't make any difference, I normally don't understand, but WOW for the first time i got something, like, in my life. I even cried a little. thank you so much, you're a hero professor!

N1gga why'd you cry? Thats so cringe 😬😂

I never knew that I could learn the topic of 5 hrs in 12 mins ! TYSM

The one who made this video is a legend 💯

I see below that someone pointed out that deriving the rate of the forward and backward reactions cannot be done by looking at the coefficients., but rather must be experimentally determined. The equilibrium constant can, however, be found by the coefficients. Kr and Keq are fundamentally different as can be seen if you do the work to find the units.

I was very confused but after watching lots of videos and the same scenarios come up, I leaned quadratic equations and now I get it. It took a week.

Thank you allot, this will really help tomorrow in my Chemistry 1A exam.

I have a question regarding the last problem. Why is that the reactant gained the +2x as its change in molarity when the whole reaction is product favored based on the value of Kc?

The most comprehensive video about chemical equilibrium on YT

this is pretty important for the AP chem test

literally thank u so much, this was so helpful

this is so high quality and well explained. ty!

thank you so much, it's brief and easily understood

I am enjoying , bcoz of what you are explaining it is easy to understand , thank you!

Thank u sir ur video is too good Please make up like this cideos

amazing explanation. thank you!

can you please make a video mainly on examples of questions on equillibrium

Excellent and nicely explained. You are a good teacher.

How do you get those initial molarities

Hi!I am chiamaka pls how did u get the value of x as 0.2 I means what was the quadratic equation you used to have the value of x.Thanks

Sorry Im a little confused at 3:10 how did u derive the rate equation for the Haber process from the stoichiometric ratios? I see how you are trying to derive K from the rate constants but... the order of a reaction is not equivalent to the coefficients from the equation.

most often the rate law can be taken from the coefficients of the balanced equation, although you are correct that there are many exceptions to that, and you need to do kinetic studies to determine it. However, I did not intend to go through exceptions in a video that focuses on the basics. Equilibrium is intricately tied to kinetics. One may incorrectly think, for example, that the equilibrium expression of an Sn1 reaction is different from that of an Sn2 reaction; however, both reactions include the activity of the nucleophile in the equilibrium expression because the true full rate law of an Sn1 reaction actually includes the nucleophile and the leaving group. That is just one exception.

Why dividing the conc of NO2 BY N2O4 instead of other way round since NO2 a product not a reactant in example 2???

For the last question, why wasn't the moles(0.95) changed into molar concentration by dividing by 10L?

it is a 1.0 L container, not 10 L. If it were 10 L, we should divide by 10.

After struggling so much I finally found this video

hey..with the last question i don't get why we had -x and not +x

Thank you so much, you're a life saver

Jeez, did i just understand this? Yes i did, sir. Thanks a lot, my book has spent around 20 pages talking about this but it makes no fucking sense. Thank you!!!!

The equilibrium concentration of CCl4 must be 0.024 moles.

Good & helpful explain👍 This video help me a lot to understand this subtopic more Thank you

I am finding this way more complicate than how explained in my class.. I don't understand all the x and those extra calculations here

plz make a video on organic chemistry

7:45 can somebody explain what he just did here, why 0.88÷5, please explain

@rishmakumar3644

He did this to get it into the concentration, i.e. [concentration (M or mol/L) = moles (mol)/volume (L)], since Kc is measured using the concentrations of each reactant and product. If he did not divide 0.88mol/5L to get 0.176mol/L then he would've only had the moles. He also converted the moles of CCl4 to concentration in the beginning too. Sorry if my explanation is a bit all over the place. Hope this helps

I feel like you confused the molarity of CCl4 to be .176 when in fact in appears to be the value we used to plug into X. CCl4 should be .024 molarity. Therefore, in the fraction where you have Kc = (2(.024))^2 / .176 ---> .176 should instead be .024.

nope, 0.176 comes right from the data in the question. It is correct.

Where is the 0.024 coming from??

Surprisingly...my lecturer watches your videos...uses ur concepts...and your questions too😂...I'm getting my fees back
