The " reaction coordinate " plotted along the abscissa represents the changes in atomic coordinates as the system progresses from reactants to products. In the very simplest elementary reactions it might correspond to the stretching or twisting of a particular bond, and be shown to a scale.

Chemists classify chemical reactions in a number of ways: by type of product, by types of reactants, by reaction outcome, and by reaction mechanism. Often a given reaction can be placed in two or even three categories, including gas -forming and precipitation reactions.

Chemical reactions, despite their staggering diversity, are often classified into a few broad types based on how atoms and molecules interact and rearrange. One of the most familiar categories is the synthesis or combination reaction.
The five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion. Analyzing the reactants and products of a given reaction will allow you to place it into one of these categories.
When chemical reactions occur, the atoms are rearranged and the reaction is accompanied by an energy change as new products are generated.

There are six different types of chemical reactions. In this article, I give descriptions and examples of each type.
In this module, we will consider and provide some context for a few categories of reactions, specifically: synthesis, decomposition, single replacement, double replacement, REDOX (including combustion), and acid-base reactions.
The purpose of energy profiles and surfaces is to provide a qualitative representation of how potential energy varies with molecular motion for a given reaction or process.
A reaction energy profile is a graph of potential energy vs. reaction coordinate that shows how energy changes as reactants become products. Read it like this: the left point is reactants, the right is products, and the peak is the transition state (activated complex).
Chemistry students often ask, “What exactly happens to energy while a reaction runs?” A reaction energy profile answers that question. Therefore, learning how to read these graphs makes predicting reaction speed and heat flow much easier. This guide breaks the idea into friendly steps, clear examples, and quick checks.
ΔG° reflects the net energy change for the reaction, but ignores energy changes as the bonds break and reform. We can illustrate this through a "potential energy diagram" (often called a reaction profile).
The x-axis represents sequential time events, or stages of the reaction. The y-axis represents the free energy associated with the structural changes taking place during the transformation.
Because a reaction cannot proceed faster than its slowest step, this step will limit the rate at which the overall reaction occurs. The slowest step is therefore called the rate-determining step (or rate-limiting step) of the reaction.
Graphs that show the change in energy as a function of the progress of the reaction are known as reaction coordinate diagrams or reaction profiles. In this topic we will look at the most common types of reaction profiles.

To involve is to bring more or less deeply into something, esp. of a complicated, embarrassing, or troublesome nature: to involve someone in debt. To entangle (usually passive or reflexive) is to involve so deeply in a tangle as to confuse and make helpless: to entangle oneself in a mass of contradictory statements.
