I have watched 3 other videos and this was by far the best one Thanks for dumbing it down a lot

Example for rate of disappearance 4:38, rate of appearance 8:46

Your explanations are very clear and easy to understand. Thank you so much sir.

I literally don't remember doing this in AP Chem but this is so helpful because my teacher put it on a homework assignment and the AP exam is coming up. Thanks!

How was the exam?

excellent. Simple and the various examples were what I needed. Thank you

Rate of change with coefficients @ 9:32 Overall reaction rate @13:30

Very helpful 👍

Thank you very much Mr. Romero, this was a very helpful explanation and it aided me in my endeavors in AP Chemistry in the 2023 year.

So clear!!! :)

awesome! thank you!!!

what if there are 3 rate of constants are given in the question??

Thanks

Thank you so much, this video was very helpful!

Mr. Romero, I have always been confused about the "overall rate of reaction". There is a problem in the National US chemistry olympiad in 2014, Problem 5 letter c , given experimental data and asked to calculate K, the answer key just used the rate of formation of of No2 instead of dividing it by 2 to use the overall rate of reaction to calculate K. Are they correct or should I still use the overall rate of reaction to calculate the value of K from experimental data?

Hi there. I'm so sorry I didn't respond sooner. I hadn't been checking the comments on my videos consistently. The rate constant, k, is a constant of proportionality that when used in the experimentally determined rate law, will lead to the calculation of rates of disappearance or appearance for the reaction in question. However, the rate constant is not the rate itself. After completing parts a and b for the question you mentioned, you should have the experimentally determined rate law. Rearrange the equation for the rate law so you get an equation for the rate constant, k. Then plug the data from any of the three trials to calculate the rate constant.

Wow❤👏

THE DRAWING SHOWS THE PROGRESS OF REACTION 2A-> A2: ​ibb.co/12cgBL3 Based on the drawing, conclude at what time the composition of the reaction mixture will correspond to drawing D. I do not understand the procedure of this task, so I ask for help. Thank you

its intresting videos

Most detail one, other people’s video just make me more confused

Thanks for your help, Sir. Why is the rate of disappearance of oxygen [-5.51x10^-3]? I thought rates are positive.

For rates of disappearance of reactants, since the concentration of the reactant diminishes over time, this would produce a negative slope when plotting the concentration vs time for the reactant (though the shape of the plot will vary depending on the order of the reaction with respect to that reactant.) The negative sign adds mathematical context for the rate as a rate of disappearance.

6:20, why does it have to be the same?

@franklinromero1215

The coefficients for both reactants are the same as each other. As a result, the rate of consumption for both reactants will also be the same.
