A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. [ 1] When chemical reactions occur, the atoms are rearranged and the reaction is accompanied by an energy change as new products are generated. Classically, chemical reactions encompass changes that only involve the positions ...
Chemical kinetics. Chemical kinetics, also known as reaction kinetics, is the branch of physical chemistry that is concerned with understanding the rates of chemical reactions. It is different from chemical thermodynamics, which deals with the direction in which a reaction occurs but in itself tells nothing about its rate.
Organic reactions can be organized into several basic types. Some reactions fit into more than one category. For example, some substitution reactions follow an addition-elimination pathway. This overview isn't intended to include every single organic reaction. Rather, it is intended to cover the basic reactions.
A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction.

In polymer chemistry, polymerization ( American English ), or polymerisation ( British English ), is a process of reacting monomer molecules together in a chemical reaction to form polymer chains or three-dimensional networks. [ 1][ 2][ 3] There are many forms of polymerization [ 4] and different systems exist to categorize them. IUPAC ...
In chemistry, a reaction mechanism is the step by step sequence of elementary reactions by which overall chemical reaction occurs. [ 1] A chemical mechanism is a theoretical conjecture that tries to describe in detail what takes place at each stage of an overall chemical reaction. The detailed steps of a reaction are not observable in most cases.
INTRODUCTION Redox reactions are a type of chemical reaction involving the gain and loss of electrons by electron transfer between diferent chemical species. This type of reaction is essential for many basic life functions such as respiration and photosynthesis. It is also the basis for many everyday processes found in batteries, breathalyzer ...
Photochemistry. Photochemical immersion well reactor (50 mL) with a mercury-vapor lamp. Photochemistry is the branch of chemistry concerned with the chemical effects of light. Generally, this term is used to describe a chemical reaction caused by absorption of ultraviolet ( wavelength from 100 to 400 nm ), visible (400–750 nm), or infrared ...
