I love you wholeheartedly, explained in 15 mins what took me watching 2 hours worth of lectures couldn't to understand.

[@ChadsPrep]

Thanks Shahrob! Exactly the feedback instructors love to hear! Happy Studying!🙂

[@lizharding2411]

Finding your channel and website was a god send! Here’s to a successful chemistry semester!

[@ChadsPrep]

I'll second that! Be sure to get plenty of practice!🙂

[@Frankvega96]

Thank you so much for this awesome video! Your teaching quality is outstanding!

[@atulkumargupta4774]

I am from India and this is the first time got something from chemistry, thanks to you for visualize me the concept so clearly

[@ChadsPrep]

Glad to hear it!

[@aleli9204]

i miss teaching my students face to face, sir. btw thank you for this! i'll be teaching it tomorrow to my grade 12 students and it's quite tricky and confusing. so far it's only your tutorial that i understood clearly.

[@ChadsPrep]

You are welcome, eli - have fun teaching the grade 12 students!

[@YunxinKuang]

Best chemistry teacher ever

I can imagine it, Hannah!

Perfect job 🤍

[@ChadsPrep]

Thank you!

[@用youtube学习的小伙子]

It is actually 0.693/-k right? For half live Since first order is ln(1/2)=-kt Therefore will be [Ln(1/2)]/-k instead of k only? But that's kinda weird as if -k we will get negative value for time. Is it just we simply ignore the minus sign ?

[@triple_gem_shining]

Its a decay rate.

[@triple_gem_shining]

So it's how much of something is going DOWN or being LOST over time.

[@fatemeh4531]

Hello. Is there A general relation of the integrated velocity law for each order?

[@frogpancakes]

You are such a chad.

[@ChadsPrep]

Happy Studying!

[@ericmora6287]

So can you use the equation ln([A]/[A]o)=-kt for all integrated rate laws or is it limited to some Integrated rate laws?

[@ChadsPrep]

You can only use that equation for 1st order reactants. The zero order and 2nd order reactants have different integrated rate laws. Now 1st order is the most common example you'll come across and all radioactive decay is 1st order, but you will still come across zero and 2nd order reactants here and there. Hope this helps!
