Chapter 18, Problem 18.13P

(a)

Interpretation Introduction

Interpretation:

The model for a second-order reaction that takes place in a real reactor is to be proposed and the values of the model parameters, $\text{α}$ and $\text{β}$ are to be stated.

Concept introduction:

Real reactor is defined as the process vessel which is used to perform a chemical reaction. It is modeled by various combinations of ideal reactors. The conversion, X can be defined as the moles of any species A that are reacted per mole of A fed in the reactor.

The full form of CSTR is Continuous-Stirred Tank Reactor. This reaction has its application in the industrial processes. This reactor actually used for liquid-phase reactions.

The full form of PFR is Plug-Flow Reactor which consists of a cylindrical pipe and it is used for the gas-phase reactions. It is also known as tubular reactor.

(c)

Interpretation Introduction

Interpretation:

An explanation regarding the changes in model and conversion is to be stated if the outlet tracer concentration was as follows:

For $t\le 10\text{min}$, then $C_{\text{T}}=0$.

For $t\ge 10\text{min}$, then $C_{\text{T}}=5+10\left(1-e^{-0.2\left(t-10\right)}\right)$.
