Chemical reaction engineering

Just by the name Chemical Reaction Engineering, it sends chilling fears to most of the students. There are students who often have a phobia of chemistry. It’s understandable. Science subjects are normally not easy and require you to rack up your brains to find solutions. Here things worsen because of the term chemical reactions. By your nerve impulse, you can associate them with chemical equations. But do not worry, we will help you understand the basics of chemical reaction engineering in this article. We won’t go deep into listing and defining some chemical equations, but this article would gear you up to know the complexities behind this topic. We would also suggest where you can get professional chemical reaction engineering assignment help if you find yourself stranded with a complex assignment.

What is chemical reaction engineering?

As the name suggests, chemical reaction engineering is a study of chemical reactions. This is one of the specialties of chemical engineering or industrial engineering. Some of the names used to refer to chemical reaction engineering are reaction engineering and reactor engineering. This is a very wide area of study encompassing chemical reactions, reactors, and catalysts.
It’s the job of a chemical engineer to select the appropriate chemical transformation, the best chemical reactor, and a catalyst. The job of a chemical engineer is also to take into consideration issues such as costs and environmental concerns.

Chemical engineering

Chemical engineering is a discipline that falls under engineering that utilizes the concepts of mathematics, physics chemistry, and biology to turn raw materials into finished products. Let’s take the example of cooking oil. The raw materials used to make cooking oil include soybeans, palm fruit, rice bran, among others. Turning the raw materials into the finished product that you often see is a special feature of chemical engineers.
Students studying chemical engineering should expect to work with a plant manufacturing industry as most of the chemical engineering concepts are applied there. In most cases, since you will be dealing with real chemicals, you will spend most of your time in the laboratory.
The effort and the time is taken to grasp its full concepts is worth it as it’s one of the high paying careers, and there are lots of job opportunities. If you are studying it, beware of the handwork that is needed.

Chemical reactions

Chemical reactions are the core of chemical reaction engineering. It’s a process by which substances, normally referred to as reactants, and are transformed into another product. The reactants are normally in the form of chemical elements. During a chemical reaction, the atoms of the substances are rearranged and form a new substance. The new substance created usually has a different property.
Changing the rearrangement of the atoms to a new one is just a superficial explanation of how chemical reactions occur. A deeper explanation of this is in the form of bonds. In reality, Atoms are the smallest components of any substance. They are only visible via a microscope. The atoms are held together by bonds. During a chemical reaction, these bonds are broken down. Breaking down these bonds requires energy. When broken, the bonds are left to be allowed to reassemble, thus, forming a new substance.
Chemical reactions are part and parcel of our lives. Almost everything that we do or use incorporates chemicals. From bear brewing, cooking eggs, burning fuels, and even the simplest act of washing clothes using a detergent is a chemical reaction. Since chemical reactions are everywhere, it’s easy to confuse them with physical changes. Physical changes are a change of state. For example, water changing to ice or vapor.


A catalyst is a substance used in chemical reactions to hasten the process. This substance, however, has no effect on the final product. Again, they are never consumed in the reaction process, and for this, small amounts of the catalysts are needed in a chemical reaction. They do take part in the reaction but remain unaltered in the end. The antonym of a catalyst is a reaction inhibitor.
You might be questioning how these catalysts hasten the chemical reaction process? Well, the catalysts often provide another pathway that requires a lower chemical activation energy. A reaction inhibitor produces an alternative pathway with high activation energy.
 There are different types of catalysts. They include heterogeneous catalysts, homogenous catalysts, photocatalysts, enzymes and biocatalysts, Nanocatalysts, and tandem catalysts.


A chemical reactor is an enclosed space where all chemical reaction takes place. There are various designs of chemical reactors that can be used, which you will learn in chemical reaction engineering. A reactor might seem like a trivial thing when it comes to a chemical reaction, but they have an effect on the overall process in terms of efficiency and cost. There are different types of reactors that vary in size and capabilities. A company has to choose the right reactor, which ensures that its operations run efficiently.

History of chemical reason engineering

Chemical engineering is a relatively old discipline that was started in the nineteenth century, but lots of concepts about chemical engineering started in the 1940s. Chemical reaction engineering has its origin around this time, and the place of origin is the shell Amsterdam research center. But the term was coined during the first European symposium in Amsterdam.

Role of chemical engineering in the present world

Initially, chemical reaction engineering was applied only to petrochemical industries. However, in recent times its use has extended to other fields such as biotechnology and microelectronics. What is its role in the present world?
Chemical reaction engineering has played a role in pushing the economy forward. Products developed as a result of chemical reaction engineering are sold and help to generate revenue. Note that most industries have to use chemical reactions to develop their final product. Economic advantages associated with such industries are vast.
Chemical reaction engineering also plays a vital role in environmental conservation. In the past, processing industries used to emit a lot of smoke, which resulted in air pollution. Now, most of the companies have adopted the use of reactors, which has a low effect on the environment.

Chemical reaction engineering using Matlab

 If you are looking for software that would help you during your project, then Matlab should be the one. With it, you can model a chemical reaction process and simulate it. From there, you can know the speed of any reaction, which is used to design a reactor. You can also monitor the real rate of a chemical process and plot its values on a graph to analyze it. It’s an indispensable tool in any engineering project. Further, you will like it for its ease of use. It takes a short time to develop a matlab code as compared to other high-level programming languages.

Matlab function for Runge Kutta method, Chemical Reaction Engineering

In this sample MatLab assignment, the subject matter expert is demonstrating to develop a Matlab function to solve problems using the 4th order Runge Kutta method. The expert has also tested the implementation of this function in two problems. Both the problems are from the chemical reaction engineering domain that involves finding the steady-state concentration and use of mass balance principles, etc
