Question $-$

The reaction A $->$ B $+$ C$,$ is to be carried out in a PFR with a co$-$current heat exchanger instead of the CSTR$.$ Set up the equations that you would need to solve for conversion AND to plot and analyze the reactor and coolant temperatures as a function of PFR volume. Include all equations that you would need to enter into Polymath except for explicit equations defining constants or initial and final conditions.

b$)$ What modification$($s$)$ would you need to make to your equations if you were to use a counter$-$current heat exchanger instead? Write any equation$($s$)$ that would need to be modified.

c$)$ Please advice what topic this type of question will be under in a chemical reaction engineering textbook, thanks
