14.4 Collision Theory and the Arrhenius Equation | General Chemistry

[@weeeeeoow]

Could watch this man's lectures for hours! Well explained, lesson enjoyed! Thank you!

[@ChadsPrep]

We have enough videos to keep you busy for that time - You're welcome and Thank You!

[@analuzramos110]

Thank you! I tried reading the textbook on this topic and did not understand at all, saw your video and read it again and now I understand what I’m reading. I appreciate all your videos.

[@ChadsPrep]

Glad you found the channel, Analuz!

20:44 how come it’s t1-t2 instead of t2-t1 as the formula says?

[@bongamajozi5788]

Thank you, Chad, God Bless.

[@ChadsPrep]

You're welcome and to you also!

The best teacher ever 🎉

Thank you

This is so dope. I'm a big chemistry fan. From ln k = ln A - Ea/RT you could repeat a reaction at different temperatures and plot ln k on the y axis, 1/T on the x axis then use the slope of a linear regression to estimate Ea (Ea = - R * slope), this assumes you can figure out k though which may or may not be difficult

[@realcirno1750]

OK, I happened to write this comment before i got to the part where you explain this exact thing 😅

[@ChadsPrep]

Haha... maybe I can read minds!

[@oryo1074]

your videos make me feel like i have hope in chemistry

[@ChadsPrep]

Glad they do!

Thank you, Chad! I hope you have a nice day too man 🤙🏽

[@ChadsPrep]

Thanks, Nicholas!

[@glassw1ng]

Thank you so much! You have quite literally saved my life.

[@ChadsPrep]

You caught the life-preserver! - Happy Studying!

[@water6133]

thank you so much!! it is all become clear for me now

[@ChadsPrep]

Awesome! I'm glad it helped

[@buffylloyd1860]

Thanks you so much for all of your fabulous teaching videos!!

[@ChadsPrep]

You are very welcome and Thank You!

[@johnmosheim]

one suggestion since units are supper important, when referring to moles specify mole = gmoles or kgmoles or other? otherwise for guys like me it leaves me guessing…thanks a ton. ps I’m a ChemE.

[@ChadsPrep]

While this may be helpful for you, it would likely confuse most of the general audience. In general chemistry, we don't even present the idea of kgmoles; it's always gmoles, and therefore in general chemistry, moles is simply synonymous with gmoles. Hope this helps!

[@timothymilsom1392]

My textbook gave me one paragraph on this... Really appreciate the help!

[@ChadsPrep]

Glad you found the channel, Timothy!

Hi! i just want to clear this up. So, In determining the In k1/ Ink2 will just depend on what you choose, it will not be based on the formula or something? Please answer 🥺

[@zp_suki2836]

Thank you!! It’s so well explained

[@ChadsPrep]

You are welcome!

[@ilaydaozkardesler]

Great explaination ❤️

[@ChadsPrep]

Thank you

Hi Chad. I'm wondering if you could help me with a problem I'm stuggling with. I'm trying to add ionic reactions into an ammonia oxidation mechanism I hope to use with a simulation platform (Chemkin). I'm trying to ascertain the parameters for the modified Arrhenius equation(K=AT^B exp⁡〖(E_a/RT)〗) from the rate coefficients of reactions I got off a database. The database only lists the rate coeff at a single temperature so how, if at all possible, do I get the A, B(temperature factor) and Ea? Do you know of any databases that actually list the Arrhenius equation parameters for reactions? Sorry if the question is inappropriate for this video's comments.

[@user-gp4yy1nq1f]

Really helpful

[@ChadsPrep]

Glad to hear it

[@RohitRaj-ve7ly]

Great explaination

You're welcome.

[@TimothyFernando-yj9wr]

Or how did it change

[@jasjeetgill3130]

u are a lifesaver

[@ChadsPrep]

Excellent!

[@sehrishrubab5767]

Which country are u from?

[@ChadsPrep]

USA - Happy Studying

[@TimothyFernando-yj9wr]

Why did the 25⁰C change

[@ChadsPrep]

Hey! Can you give me the time in the video for this question?

[@TimothyFernando-yj9wr]

@@ChadsPrep ohh thanks I got the answer

[@haneen1920_]

The best man 🥹💕! I learned a lot on your channel

[@ChadsPrep]

Excellent!
