Types of Chemical Reactions

Today we’ll be going over just a few basics elements of what chemical reactions are about.

Today, we don’t have the time to go through this in full depth or thoroughly. Here, we’ll just go over a few of the common basics regarding chemical reactions.

When we’re thinking about chemical reactions, a key thing to keep in mind is time scale. This means how slowly or rapidly does a chemical reaction take place.

Obviously, when we’re looking at the time scale, we measure the time scale from our human vantage point or viewpoints.

So we measure on our human time scale, in the way that we are experiencing time.

A chemical reaction may happen very rapidly. It can happen very quickly but also very slowly. From the low end, it might take just a fraction of a second in which a chemical reaction takes place, or it may, at the upper end, take years and years before chemical reactions fully have taken place and, of course, then also everything in between.

When dealing with a chemical reaction, our time scale might be from fractions of a second right all the way up to many years for these reactions to take place and, of course, everything in between.

When we’re thinking about the time scale, we’re also thinking about reaction rates. Now, what is affecting reaction rates? In chemical reactions, we should be thinking in terms of frequency of contact between the various chemical components that are involved in the reaction. when we have just little contact, we’ll have a slow rate. The components do not get into contact so often. On the other hand, when we see a great mixing of the components that react volatilely, you may create a rapid reaction. It is about the frequency in contact between the chemicals that are interacting.

Then, temperate plays also a role. Higher or lower temperatures may affect not just the chemical reaction, but the time rate as well, and also the properties of the interacting chemicals. Are we dealing with solids, liquids, or perhaps a gas? What’s the shape of the chemical? Well, all of these sorts of things are playing a part when we consider the reaction rate, temperature, frequency, or properties. And when we’re looking at reaction rates, we actually are able to influence these rates. We can accelerate reaction rates. This happens when we use a catalyst.

When a catalyst will be introduced to a chemical reaction, it will greatly speed it up. That is the only job of a catalyst. It comes into the interaction between chemicals only to speed up the reaction. A reaction that would ordinarily take a longer period of time to happen will rapidly increase when a catalyst is added. We may also decrease the rates of a reaction. This is done by using so-called inhibitors. When we introduce an inhibitor into a chemical reaction, the reaction will slow down. It will keep the chemicals from reacting just as quickly.

We can affect our reaction rates. Not just naturally and in ways that we’re able to control the temperature and the form or shape it is in, that sort of things. But we may use another chemical catalyst to accelerate or an inhibitor to decelerate the time of our chemical reaction. Now, a chemical reaction can, when they’re occurring, release heat, electrons, release light, or ions or something else that’s the product from the interaction, from this chemical reaction that is taking place.

Sometimes, a chemical reaction will send the temperature right in the opposite direction. Usually, though, it’s just things like light or heat, or electrons that are traded or ions that are spun off, or radicals going spun off, just things like that.

Finally, heat and some other factors may influence a chemical reaction and help to break bonds. Just think of this like in breaking carbon bonds. Obviously, this occurs when we produce oil and other related materials. We have some strong and stable carbon bonds which we must break down and it split up. Generally, we use primarily heat for breaking up these bonds, then we divide those things further up and later again sort these things out to their various purposes and functions.

If you may ever do some study or research, see how fascinating it can be to look at a chemical or oil plant and see how the raw materials are brought in, how they use heat or pressure and things like that for breaking up the raw materials into a number of other materials.

Then they will be sifting it out and later send it to other places for other uses; it’s really fascinating. This chemical reaction part is just a basic overview and again, timescale may vary from a fraction of a second to years and years and more years.

The reaction rate is affected by contact frequency, the temperature when the components are mixed, their contact. Then we should look at the properties, and if it’s a solid, a liquid, or a gas (and the shape of it), that sort of things. T

he reaction rate may be accelerated with a catalyst and decreased with an inhibitor. A chemical reaction produces often things like heat and light and spinning off electrons and ions and things like that.

Heat and some other factors may influence a chemical reaction and help break down chemical bonds.
