thank you so much I’ve struggled a lot to understand this! Because in our slides it’s so complicated 😢it’s 3 AM and my final exam is at 12 PM and literally you saved my life I have fully understood this thanks Amanda❤

Awesome video I finally understand rate laws

You explained this so clearly, thank you!

Thank you !

Thank you ma'am ❤️

this was so helpful ahh thank you

I doubt you're still responding to comments on this video but its worth a shot. I have a problem on my homework that I simply don't understand related to this because we did not cover it in class and it seems to be way beyond the scope of the course curriculum. We are meant to cross out the intermediates of a multistep rxn and also show the overall equation. This is where I am lost The problem is generic. It is: U ---> V V ---- W + X W + Y ----> Z (RDS) I believe the rate law is r= k[W][Y] and that it is a second order rxn. However, W seems like it should be an intermediate. We did not learn anything related to what is presented in your video during class. I have watched my professor's pre-recorded lecture IDK how many times and compared what she was saying to what you are saying. Is there something I am missing? Thank you :)

But Miss, what if the reaction A+B-->C is not reversible, could we have used the same reaction? What if A and B just formed the intermediate and the C reacted with D?

Thats a very different issue and one that we don't cover in my classes since you need to have more information. Some general chemistry textbooks talk about it but in most case you'll need to get ahold of a junior level kinetics book.

Why can't intermediate be in rate law

@@shanthala1345 that’s how I made it stick. But yeah it does exist but it’s formed in on step and consumed in the next, it’s not present right at the beginning but is formed after the reaction starts. This is why we can’t include it in the rate equation because in the overall reaction the intermediate isn’t there
