4. Identify and Name:

Relative Theories and Equations Algebraic Form of CSTR equation: derive CSTR volume
For reactors in series, such as a PFR after a CSTR, the integral form of a PFR equation becomes: derive PFR volume

2. Systems

Volume of PFR

Volume of CSTR

3. Dependent and Independent Variables

Independent: V_CSTR, V_PFR, F_A0, F_B0, T

Dependent: k, X₁, X₂

4. Knowns and Unknowns

Knowns: same as Part I

values of knowns

Unknowns: conversion from CSTR, X₁

conversion from PFR, X₂

5. Inputs and Outputs

In: same as Part I

Out: same as Part I

same as Part I

Combine: 

steps in combining

Evaluate:

evaluating for X₁

evaluating for X₂

Check units, X is dimensionless.

With a CSTR upstream of the PFR, the conversion increased from 0.5 to 0.684.
