14.2 Rate Laws | General Chemistry

[@samanthasanchez7098]

Chad, no words can explain how thankful I am for your easy and concise explanation of the topic. I don't usually leave comments on KZbin, but I seriously have to express my graditude. I am someone who struggles with chemistry, causing me to panic weeks before exams and quizzes. After watching your video can I just say that it all clicks now? The car analogy, the arrows you drew when explaining the doubling, it may not mean much to you but these actions truly played a role in my understanding of the topic. From one of the many students you've helped, thank you.

[@ChadsPrep]

Thank you for the kind words - I appreciate your comments. It is gratifying to hear that your understanding is deepening. Happy Studing!

[@red1307]

You better name your firstborn "Chad"

[@genevieveaiwonegbe8615]

This man is constantly saving my Gen Chem Grades. We say thank you.

[@ChadsPrep]

You're welcome!

[@abdoulazizdabo9064]

You’re the best professor, wish many students can discover these valuable videos. Thank you

[@ChadsPrep]

Glad you find the videos so helpful :)

[@andremejia888]

You sir are truly a noble gentleman. I read the chapter in the textbook on this subject and attempted the practice problems: failed. I watched your video and then re-attempted the SAME practice problems: easily completed. Mr. Chad is not the hero we deserve, but the hero we need

[@ChadsPrep]

Glad the video is helping, Andre - Happy Studying!

[@tednosaur6257]

I cannot thank you enough for this video! You explained what I didn’t understand in just a couple of sentences! Thanks for getting straight to the point, definitely gonna check out your prep courses.

[@ChadsPrep]

Glad to hear it, Nina - Happy Studying!

[@Patrick.Holland]

absolutely incredible video, tied everything together perfectly in the end as well. I got a A in gen chem 1 last semester and went into gen chem 2 overconfident, and still studied a lot for the first big exam but did extremely poorly. Exam 2 is next week on solids and Chemical Kinetics, your videos are great and extremely helpful, with lots of practice, I am aiming to do much better and a large thanks of that is going to you. Thank you from a future Dentist, your videos are life saving!!

[@ChadsPrep]

Glad the channel/videos are helping you - much success to you and your dental endeavors!

[@ltac8194]

Your videos are awesome. So succinct and precise. It's a great supplement to my professors lectures. Why you don't have more subscribers, I am stunned. Thanks so much and you've gained a subscriber in me for sure.

[@ChadsPrep]

Glad you found the channel - thanks for the sub!

[@sumnerjones8588]

Phenomenal video Chad - this was explained by our professor in let's just say *not the greatest fashion*, and you somehow delivered a succinct and effective lesson on a tough topic. Thank you for continuing to democratize education!

Mr Chad, Professor Chad, oh my gosh I think your channel just saved my Gen Chem 2 grade. Thank you so much for sharing your knowledge, I'm at a point with my chem professor where I'm not following his methods of teaching AT ALL, he seems like a great guy and his qualifications are excellent and all those wonderful things but I'm not sure he knows that we are not all PhDs lol your videos are easy to digest and very very clear to follow. Thank you so much.

[@ferrin6326]

This was really, REALLY good! I'm going to comment to boost this video. My AP Chem teacher doesn't teach us (very literally, he just assigns textbook sections), but does expect us to be able to do chemistry at a level even more advanced than the AP exam. I found this extremely helpful and am currently mourning the fact that my teacher doesn't teach, since this was so fantastic.

[@ChadsPrep]

[@nohelialovatonaragon4745]

Thank You so much! I was stuck and frustared. Thank you thank you. They should show your videos in online classes honestly, my professors had me so confused and never give good examples to solve my labs. I have a question though, how do you solve when instead of doubling or tripling, they divide, for example, from 0.02 to 0.01, what would be the order?

[@BryantLuma4647]

Thanks sir for the proper explaination

Oh my god. I did not understand the lecture at all in my class. I immedietly turned to you and am glad I did. Please do every student a solid and never stop creating. The world is lucky and fortunate to have you. Also could you also make a chem video for easily telling if a molecule is polar without the need to use full vsepr theory and without access to electronegativity numbers becuase in AP Chemistry, you only have the periodic table. Thanks :)

Welcome to the channel!

[@nasifkalanda5390]

Good lesson sir, keep saving us

[@ChadsPrep]

Glad the channel is helping you!

[@leobi1243]

I have a question here, so the rate we calculated is the rate of change in concentration of Cl2 or NO? As I understand it, the rate for NO is double that of Cl2 because of NO's coefficient, so what is the reaction rate representing here?

[@ChadsPrep]

Hi Leo! If you look back at the previous video in the playlist, I introduce rate expressions and explain that the rate of reaction can be expressed in terms of any reactant or product. The absolute value of the rate of reaction will be the same as the rate of change for a reactant or product with a coefficient of 1, half the absolute value of the rate of change for a reactant/product with a coefficient of 2, one-third of the absolute value of the rate of change for a reactant/product with a coefficient of 3, etc. This way, regardless of which reactant or product you consider, the overall rate of reaction will have the same value. Hope this helps!

[@zacharypritchett2206]

Hey Chad, what if the concentration from trial one to trial two in NO decreased, but stayed constant in Cl2? would the exponent be a fraction?

[@ChadsPrep]

Hey Zachary - yes we would end up with a fractional exponent in that case. BUT! if the NO concentration halved and the rate halved also it would still be first order :)
