Kinetics: Initial Rates and Integrated Rate Laws

Who likes math! Oh, you don't? Maybe skip this one on kinetics. Unless you have to answer this stuff for class. Then yeah, watch this.

Check out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!

Hey everyone, YouTube is deleting annotations, and there is an error at 5:41 that I had fixed with an annotation so unfortunately I must simply list the correction here! The values at the bottom right should read: 0.04 = k(0.01)(0.250) and k = 16/(M^2 * s), when making the video I forgot to square [NO] so please make that correction in your minds, sorry about that!

how did i understand this in 10 minutes but couldn’t in two weeks, honestly professor dave u out here savin lives.

[joanavillalobos]

I have my chemistry exam in 30 minutes and you just explained literally everything I need to know in ten minutes. Can you be my chem professor instead? 😭🙏🏽

"the reaction order HAPPENS to match the stoichiometric ... but this won't always be the case"


right there, professor dave has done what no fucking textbook in the fucking world has ever done. it has pointed out something that a student might mistake, by thinking the way a student might.


hats off. well done. please write a text book or ten for students who wouldn't know any better and make that mistake. i'm a 30-something year old engineer, and i'm dead serious.


you are the man.

I like Professor Dave. He tells it like it is. No messing around, pay attention type instruction in a clear and precise way. Very nice.

[raymondhee]

I am a Chemistry lecturer and I find your videos very clear and concise. Well done!

When the concentration is doubled and the rate then also doubles, the reaction is first order with respect to that reactant. When the concentration is doubled and the rate quadruples as a result, the reaction is second order with respect to that reactant. If changes in the concentration doesn't affect the rate, the reaction is zero order with respect to that reactant.

Very well done video you explained it good. I suddenly understand everything now which makes me again question why im spending thousands on tuition money...

[mathyouforgot]

I have a pre-lab assignment due and the instructions were hard to understand. you saved my butt by being smart and teaching the way it should be taught. Thank you !

[joeysantana]

Crash course: Hey so I was walking my dog on alone with my family on Christmas in the summer, and lol chemistry rate laws XD. Dave: I’m Dave here’s chemistry

[chocolatecrud]

Can always rely on this great channel for that extra bit of explanation, much appreciated

[panosr]

No joke this was a blessing. I understood more in 9 minutes than in a whole physical chemestry lecture. Thanks professor Dave

[angelarose]

Explained it better in ten minutes than my uni lecturers did in a week - thank you XD

[cameroncrowley]

This man is a legend, taught me this in 4 minutes what my lecturer couldn’t in 3 weeks

[millicentmagolego]

I'm writing my Chemistry semester test today and i had thought i'd have to sacrifice this chapter but thanks to Professor Dave i have a feeling that i'm going to nail it.

[sanjivprasad]

You know you are at the right place when Jesus himself teaches you chemistry

[elizabethlear]

I literally can't thank you enough, you make chem easy to understand

[Roadways]

He makes me understand the concept in just 9.10 minutes. What a great teacher. Hats off to you professor dave. 😃😃

[Kamilaxx]

I struggled with this for 2 years. And after those 9 minutes i understand it completely. I can't believe this..

[Josh-zkpf]

Man I love the intro i just have to hear it one more time before I start learning
