The activated complex is the intermediate form of a simple
chemical reaction
. In the following simple chemical reaction:
A + B ---> C + D
A & B are reactants; C & D are products. The activated complex can be written as A-B like so:
A + B --> A-B --> C+ D
Basically it is the complex formed when A & B "collide" together. The energy of the system increases during this collision and if it exceeds the "activation" threshold, the reaction can occur (it doesn't have to occur however. think of A-B as the top of a hill...the reaction can proceed forward, down to C & D or go backwards to reform A & B...the hill represents the energy of the system). The activated complex is also known as the transition state, or intermediate state, since it must preceed product formation.

What does H20 above arrow in a chemical formula mean?
This means that the reaction in question takes place in an aqueous solution. Even when water does not take part in a reaction, many things - most things, actually - will be more chemically active if dissolved in water, than in solid form.
What is the process of breaking down complex food molecules into simpler food molecules?
The process of breaking down complex food molecules into simpler food molecules is called digestion. It begins in the mouth with the mechanical and chemical breakdown of food, continues in the stomach where more chemical digestion occurs, and is completed in the small intestine where nutrients are absorbed into the bloodstream. Enzymes play a key role in this process by breaking down larger molecules into smaller ones that the body can use for energy and growth.
Living things play no role in physical or chemical weathering?
Actually, living organisms can play a significant role in both physical and chemical weathering processes. For example, tree roots can break apart rocks through physical weathering, while certain microorganisms can produce acids that contribute to chemical weathering. In general, the presence of living organisms can speed up the weathering of rocks and minerals.
What is the role of ethanol in saponification?
Ethanol is sometimes used in saponification processes as a solvent to dissolve oils and fats, which helps facilitate the reaction between the fats and the alkali to produce soap. Ethanol can also act as a catalyst to speed up the saponification reaction.
What is Refractory organic matter?
Refractory organic matter is organic material that is resistant to decomposition by microbial or chemical processes. This can include substances like lignin or complex organic compounds that are difficult for microorganisms to break down. Refractory organic matter can accumulate in soils over time and play a role in soil carbon storage.
How does conversion reaction chemistry play a role in the transformation of substances during a chemical reaction?
Conversion reaction chemistry involves the transformation of substances during a chemical reaction by changing their chemical composition. This process plays a crucial role in converting reactants into products by rearranging atoms and forming new chemical bonds.
What is the chemical reaction role of energy?
energy is released or absorbed.
Nearly every chemical reaction in the body is activated - assisted - and controlled by?
enzymes. Enzymes are biological catalysts that speed up chemical reactions in living organisms by lowering the activation energy required for the reaction to occur. They are specific to particular substrates and play a crucial role in metabolism and other biochemical processes in the body.
What is the role of enzyme in cells?
enzyme sped up the chemical reaction
What is the role of a reagent in chemical reactions?
A reagent is a substance that is added to a chemical reaction to cause a chemical change or to help facilitate the reaction. Reagents can help start a reaction, speed it up, or control the outcome. They are essential for many chemical processes to occur.
Which is defined as new substances formed from chemical reactions?
Chemical reaction, a process in which one or more substances, the reactants, of a chemical reaction had a primary role in defining the science of chemistry as it is known today.
What is the role of a manganese in a reaction?
See for the biological role at: http://en.wikipedia.org/wiki/Manganese.
What best explains the role of a catalyst in a chemical reaction?
A catalyst is a substance that speeds up a chemical reaction by lowering the activation energy required for the reaction to occur. It does this by providing an alternative reaction pathway with a lower energy barrier. The catalyst itself is not consumed in the reaction and can be reused multiple times.
What happens to a product during a chemical reaction?
The product doesn't exactly provide a role in a chemical reaction, but rather is the result of the chemical reaction occuring. The chemical reaction may occur specifically to produce that product to be used, and it then serves a role in that respect, but generally products don't play a role, but are just the outcome.
What is an intermediate in a complex reaction?
An intermediate in a complex reaction is a molecular entity that is formed during the course of the reaction but is not the final product. It typically exists transiently and is further transformed to give the final product. Intermediates play a crucial role in determining the overall reaction pathway and product formation.
What role does a catalyst play in science?
A catalyst reduces the energy needed to start a chemical reaction.
What role does a nucleophile play in a chemical reaction as a base or acid?
A nucleophile acts as a base by accepting a proton in a chemical reaction, while it acts as an acid by donating a proton. In both cases, the nucleophile participates in forming new chemical bonds.
