Comments: Good introduction of showing the mole balances for multiple reactions. Multiple Reaction Rates need to be covered in a separate to show the algorithm of Rates: 1) Net Rates, 2) Rate Laws and 3) Relative Rates.

Comments: There is a strange definition of rate (which is not strictly correct and will not apply to many systems) being defined without a subscript with respect to a particular species at the start of the video. However, after that, -ra is used and everything is ok. Good explaination on how to set up PFR mole balances for multiple reactions.

Comments: Good Example! (A + B -> R + S), pseudo first order reaction -rA = kCA CB = kCB0CA = k'CA. This problem could probably be more easily solved using conversion.

Comments: A -> B (-rA = kCA) problem could also be easily solved using conversion.

Comments: Liquid catalyzed reactor
, 
, B is not consumed and is fed to the reactor at a rate of FB0.
The mole balances are: dNA/dt=rAV, dNB/dt=FB0, and dNa/dt=rcV.

Comments: Good example and everything is correct up to the Polymath program where they are compensating minus sign errors in the mole balances and in the rate laws. The minus signs are missing in the mole balances as they should read dFA/dV = rA and dFB/dV = -3rA and in the rate law in the Polymath program should then be rA = -kCT0(FA/FT).

Comments: Good application that complements the drinking and driving home problem on page 329 of Essentials of CRE
