14.1 Rate Expressions and the Rate of Reaction | General Chemistry

- Опубликовано: 21 июл 2024
- Chemical Kinetics is often the first chapter encountered in General Chemistry 2. In this first lesson, Chad covers Rate Expressions and the Rate of Reaction. The lesson begins with how to write the rate expression for a reaction. A rate expression expresses the rate of a reaction in terms of a change in the concentration of the reactants or products over time. Then, the overall rate of reaction is introduced as well as how rate expressions allow for the determination of the overall rate of reaction from the rates of change for individual reactants or products.
I've embedded this playlist as a course on my website with all the lessons organized by chapter in a collapsible menu and much of the content from the study guide included on the page. Check this lesson out at www.chadsprep.com/chads-gener...

Currently struggling in my chemistry class, I have dreams to be a doctor and I’ve been really discouraged by not getting the information fully. Out of Professor Dave, and organic Chem tutor you’re easily as good if not better! I find your style of learning to be so easy to understand and I just want to say thank you beforehand because it’s cause of you I’m going to ace my test next week
Thanks for your kind words - all the best in your academic endeavors!
prof dave sucks lowkey... respectfuly
@@enoughnonymity prof dave taught highschool students, those classes are quite a bit dumbed down compared to college level
Thank you so much!! I seriously cannot thank you enough! You explain everything well, take it step by step, and even make really helpful analogies! I'm taking AP chem this year and it has definitely been the hardest class I have ever taken so I am very grateful you took the time to make these videos. Thank you!!!
Welcome to the channel - glad it is helping you!
Thank you very much! I've been struggling with kinetics and thermodynamics so I really appreciate this video and all of your other content! Keep up the great work! :)
You're welcome, Timothy - and Thank you!
Cool~ you are the Best! Enjoy the series of chemistry courses provided by Chad. Thank you very much and take good care during the pandemic.
Thank you, flora chen - Happy Studying!
Very organized and clearly explained...Thank you so much for your effort making these videos, it helps me a lot.
You're welcome - Thank You!
After taking gen chem 2, i realize even more how awesome of a teacher you are. Your preciseness and attitude is unmatched. I have a different teacher for the class, but youre my super secret online teacher I'll be learning from ;)
Glad the channel is helping you so much - Happy Studying!
I love the old fashioned white board style compared to the other youtube chemistry videos. Thank you your explanations make chemistry so much more simple.
Lots of students prefer it just like you. Glad you found us!
You are the best Chemistry Teacher in History
High praise - thank you.
what is the difference between the free video vs the mcat prep ones?
Thank you this helped clear up a lot
You're very welcome.
Oh my goodness that casino example gave me that ‘Aha!’ moment-made so much sense :) thanks for this !
Excellent!
You are the reason I love chemistry everytime I'm struggling I come here and watch your videos
Glad the channel is helping you.
very good explanation👏
Been loving all the feedback Science Nerd! Really appreciate it!
My teacher recommended your videos to me after I told her I was struggling, I see why!! Thank you so much
You're welcome and Thank You. And thank your teacher for me! Happy Studying!
this made so much sense
Glad it did!
You're perfect sir...am slowly improving in chemistry
That's great - Happy Studying!
Does it mean that the rate of reaction of the reactant should equal to the rate of reaction of the product?
You have literally saved my entire chem grade
Gla to hear it!
If we switched this reaction around, would the rate expression then be equal to -Δ[N2]/Δt ? Thanks for the video, super helpful!
Yes because the in reverse reaction I believe the N2 is depletingin quantity
you are amazing!
Thanks for saying so - Happy Studying!
thank you
you're welcome
It really was helpful
Glad to hear it!
Do we include catalysts in presenting the rate expression of a chemical reaction?
only if it is a reactant in the rate determining step of a multi-step reaction
@@ChadsPrep thank you sir
I have a question
We always use concentration in the form of Molarity not moles
If we have Hcl + Naoh = Na cl + H2o
That means
1 M of both Naoh and Hcl are consumed to yield I M Nacl
Acvording to the rate of reaction expression and Ratio
However if we
Add I L Naoh 1 M to 1M IL HCl
Will yield 1mole Naoh in 2L
That means
0.5 M of Nacl not 1 M
Kindly explain
Thanks
Yes sir I just understand😊
Excellent!
I love being taught by Corey Taylor's lost relative, superb teacher!
Thank you and Happy Studying!
Sir how rates of all these 3 stuffs could be equal even their stochimetric cofficients are different😮
What time is this in the video?
@@ChadsPrepsir Sorry l didn't see it😑😑😐
Spoken like a true Chad
Happy Studying!
I'm struggling in Chemistry 2. I'm a non traditional student and have been out of school a long time. My current teacher is a lovely lady however your foreign accent makes it very hard to understand her . Thank you for the videos
Glad the channel is able to help you out - Happy Studying.
totally a side question but did you watch/enjoy oppenheimer? I learned most of the important quantum scientists from your vids and my textbook lol
like the shirt
Thank you!
