Energy Diagrams, Catalysts, and Reaction Mechanisms

It's time to learn a little more about a chemical reaction. How do molecules have to be arranged and how much energy do they have to collide with? What's a catalyst? Lots of great tidbits in this one.

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

Man. I've been in my Chem class for 2 months and I've learned more from these videos in one night than all quarter. Thank you. I plan on financially supporting this channel

[Priya-qzue]

Thank you so much Professor Dave!! You got me through AP Chemistry!!

[ZaidanyZ]

Simple, flow, and generous!!!! Thank you 🙏

[arthurezeagu]

Sir your lectures are are comprehensive, I really appreciate your time

How about a little explanation of the equation next time where you actually work out an example. The concepts are easy to comprehend, it's the math that throws most of us off.

0:45 Activation Energy
Transistion State

Delta H

Exothermic And Endothermic

Catylyst, lowers the activation energy, resulting in faster reactions

I study chemistry in arabic and thank god that there is arabic subtitles or else i would translate EVERYTHING to arabic.

I followed every part of this comprehension equation up until the answer. I've been trying to catch my mistake for hours. Professor Dave, can you please give me a hint? Maybe you can simplify the left side of the equation? On the right side, I end up with Ea/-83.15 J/mol, therefore multiplying both sides by the -83.15 J/mol.

I've got the sruff about activating energy and catalyst but defenetly got nothing about equation. How that busines work...

I vow to financially support all the youtube accounts that helped me get through college after I graduate and start earning. Thank you Chemistry Jesus! Been helping me since my Senior High days.

Professor Dave what are the common questions asked when using the Arrhenius equation and what are their equations. I have only taken basic algebra. I do not know how to manipulate the equation. Never taken calculus or physics. Can you help please.

[maricelalopez]

Do you only use the equation above for all Arrhenius equation problems?

[RichardJohnson-xojb]

your opening reminds me of southpark bigger longer and uncut

[chelseavelasquez]

thank you for making these videos! how do you find the Ea in the comprehension problem. I tried to divide the value for the temparatures on each side and then multiply by 8.315 to get Ea alone but couldnt figure out how to get your answer.

thank you very much prof please I want video about specificity of catalyst

[Ari-rwhv]

You make learning chem easy, thank you

A catalyst is added to the reaction to speed up the reaction. Then why is it not found in the product? If it's not used where does it go?

[SKyoto]

Hi, watching this video reminds me of a discussion i had with my teacher. In every book i readed so far i learned that a catalyst gives a other reaction way. My teacher said thats wrong and there are many examples proof that. But actually i dont wanted to piss her of more cause i dont want to loose my A in this class. So i didnt ask for any examples. Can u give me some or is my opinion on catalyst right and my teacher has no idea ?  ;)

Hi. Can I ask where did 308k and 318k from? I'm not good in chemistry
