Elementary Rate Laws - Unimolecular, Bimolecular and Termolecular Reactions - Chemical Kinetics

This chemistry video tutorial provides a basic introduction into elementary reactions and elementary rate laws. It explains the difference between unimolecular, bimolecular, and Termolecular reactions. An elementary reaction is one in which the rate law can be written from the coefficients of the balanced chemical equation and agrees with empirical data. A unimolecular reaction is a reaction that can proceed using a single molecule. A bimolecular reaction is one in which two molecules must collide in order to react. Termolecular reactions require the collision of three molecules.

I LEARN MORE FROM YOUR VIDEOS THAN I DO AT SCHOOL. AND I PAY A LOT FOR THAT THING

[WynterRejoice]

EVERY video you've made has helped me so much. God Bless You!

[Sydrxh]

This has actually saved my life like no one will ever know how helpful this is to me LMAO

[georgesadler]

Professor Organic Chemistry Tutor, thank you for a short and sweet Introduction into Elementary Rate Laws in AP/General Chemistry. The difference between unimolecular, bimolecular and Termolecular is simple to follow and understand, however, the final example/practice problem is problematic. This is an error free video/lecture on YouTube TV with the Organic Chemistry Tutor.

Love your videos dude, they are easy to follow and they are helping me learn and that is sayin a lot !

[nataliekath]

Thankss a lot!! This thing was a really major difficulty for me

[okechukwudenis]

Please what's the molecularity of the last example he gave

[Nrahotep]

For equation 1A + 2B -> C the
rate = k[A]¹[B]², but I thought that you had to determine the reaction order experimentally. And that the stoichiometric mole ratios of the equation don't determine the reaction order. Am I right in assuming that the overall reaction order determines the molecularity?

[shulammiteoluwatunmise]

Thanks very much your the best as always 👍👍💗

[skrtsk]

I thought coefficients did not determine reaction orders??

[Rohan_Mahato]

simply, number of molecule reacting in RDS = molecularity, isn't it?

[UltraTheBeastt]

you just saved me
I have a test in a few hours and i didnt know this thanks

[VedantDaud-gmsp]

The last rate law would not be possible as it would be an complex reaction and not an elementary reaction

[principleinstitutetelugu]

Sir I have one doubt what is the difference between elementary bimolecuar reaction and bimolecular reaction

[muhammadahmad]

The last one isn't correct though.. the one u didn't solve... If that's how we do it then it's going to be a ninth order reaction 😥 how man?

[biggboss]

Your thumbnail are meaning ful from this almost are learn

[jb]

Would be nice if the instructor taught this before assigning the problem on hmwk or test. Ever tried reading a chem book? It is all proofs, no substance. Just white noise.

[srinukatrusrinukatru]

Sir please answer for this question that is molecularity of 2NO2+F2➡ 2NO2F. For this please give explanation to me sir
