Chapter 5, Problem 5.3P

(a)

Interpretation Introduction

Interpretation:

Among the given conversions, the conversion that is obtained if the PFR operated at half the original pressure is to be stated.

Concept introduction:

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

(c)

Interpretation Introduction

Interpretation:

Among the given value of rate constants, the rate constant that is accounted after the pressure drop is to be stated.

Concept introduction:

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.

The full form of PBR is Packed-Bed Reactor which is used for the fluid-solid heterogeneous reactions. These fluid-solid heterogeneous reactions take place at the surface of the catalyst.
