Very simple and interesting explanation Brian. I am a biologist, even then I could able to follow your derivation line by line. thank you

[@abdulhaseeb4513]

well explained!

at 17:16 how are you getting dC=Ko(-Ddz) ? if Ko is just replacing J then wouldn't it be 1/D and not D?

[@LouisTabosa]

You are right. But that doesn't change the final result (the value of Ko is obtained in function of D... So, when substituting it is canceled anyway). Despite this little confusion, a really nice explanation.

Thanks a 1000!! Your video was super helpful

I have a question, where come from for this equation Vd dc/dt = kL. A (Cl*-C). the origin of this equation come from Fick's law, isn't it? Where come from term of volume (V) and Area (A) and dc/dt.

Yo Aaish this is like your random walk presentation in class! I was the class clown chem e in undergrad. I liked chem e because its not mainstream like chemistry. Its for people who are good at chemistry but want to be part of a cult. Chem e is a cult major. I think police officers who worked with me should know that engineering is applied mathematics, or street mathematics.
