Chapter 4, Problem 4.4P

(a)

Interpretation Introduction

Interpretation:

The entering concentration $\left({\text{mol/dm}}^{\text{3}}\right)$ of B in PFR is to be stated.

Concept introduction:

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

The rate law of the chemical reaction states that the rate of reaction is the function of the concentration of the reactants and the products present in that specific reaction. The rate is actually predicted by the slowest step of the reaction.

If there is a chemical reaction which has reactants A and B that reacts to form products then their rate law is given as follows.

    $r=k{\left[A\right]}^a{\left[B\right]}^b$

Here, $\left[A\right]$ is the concentration of the reactant A, $\left[B\right]$ is the concentration of the reactant B and $k$ is the rate constant.
