Chapter 10, Problem 10.20P

(a)

Interpretation Introduction

Interpretation: The suitable operating conditions have to be recommended.

Concept Introduction:

Second order reaction: When the rate of a reaction is proportional to the concentration of two reacting molecules, then such a reaction is known as second order reaction

General representation of a second order reaction is as follows:

$2\text{A}\stackrel{}{\to }\text{Products}$

Rate law for second order reaction is given below:

$\begin{array}{l}\text{Rate}=\text{K}{\left[\text{A}\right]}^2\\ \text{K}=\text{is}\text{the}\text{proportionality}\text{constant}.\end{array}$

(b)

Interpretation Introduction

Interpretation:  The wrong happenings on choosing the given condition has to be found.

Concept Introduction:

Activity: It is the measure of effective concentration of a chemical species under non-ideal conditions.

(c)

Interpretation Introduction

Interpretation:  The gas velocity for the given data has to be recommended.

Concept Introduction:

Gas velocity:

The velocity of a gaseous molecule is known as its gas velocity. The average velocity of all gas will be zero in a given sample.  This is because gaseous molecules move in all random directions. So the velocity in one particular direction will be cancelled by the velocity of another gas molecule which is acting in the exactly opposite direction.

(d)

Interpretation Introduction

Interpretation: The corresponding conversion for the given data with respect to the chosen temperature has to be found.

Concept Introduction:

STTR: Spinning Tube-in-Tube Reactor: It is an area-based reactor system that has applications in petrochemical, biodiesel and pharmaceutical fields.

(e)

Interpretation Introduction

Interpretation: The appearance of temperature-time trajectory for the given CSTR has to be found.

Concept Introduction:

CSTR means Continuous stirred-tank reactor. It serves as a common model for a chemical reactor in chemical engineering. It is a mathematical model that works for all types of fluids, liquids, gases and slurries. Prefect mixing of substances can be achieved from this reactor by its action of continuous stirring.

Temperature-time trajectory: In the word temperature-time trajectory, the word trajectory literally means the path. So temperature-time trajectory means the curve that is described by the temperature and time co-ordinates.
