A very proprietary industrial waste reaction, which we’ll code as A → B + S, is to be carried out in a 10-dm³ CSTR followed by a 10-dm³ PFR. The reaction is elementary, but A, which enters at a concentration of 0.001 mol/dm³ and a molar flow rate of 20 mol/min, has trouble decomposing. The specific reaction rate at 42°C (i.e., room temperature in the Mojave desert) is 0.0001 s⁻¹. However, we don’t know the activation energy; therefore, we cannot carry out this reaction in the winter in Michigan. Consequently, this reaction, while important, is not worth your time to study. Therefore, perhaps you want to take a break and go watch a movie such as Dances with Wolves (all-time favorite of the author), Bohemian Rhapsody, A Star is Born, or Despicable Me 3. As a side note, the Jofostan Film Festival is held the last week in January in Riça, Jofostan. But don’t try to attend the Jofostan Film Festival as it’s only “A-List” celebrities such as Denzel Washington, Meryl Streep, and Sven Köttlov.
