What is the role of the activated complex in a chemical reaction?

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 role does water play in each stage of soil formation?
play a part in chemical reaction also in leaching process and in supporting micro organism activities
Living things play no role in physical or chemical weathering?
true
Role of potassium carbonate in sharpless assymetric dihydroxylation?
to keep the pH opf the reaction mass towards basic.
What is the role of sunlight in the reaction between n-hexane and bromine?
Sunlight wouldn't be enough energy to carry out the reaction between n-hexane and bromine. The energy source, however, may have been written has "hv" as a way to describe the radiation or high-wavelength energy for the reaction, which is possible in a more controlled environment. In this scenario, the reaction between n-hexane and bromine is a bromination reaction--generation of a bromine radical and attaching one or more bromine molecules to hexane. It is more likely that it will attach to a secondary carbon rather its primary, and its location of attachment between the available secondary carbons would be a mixture.
What role do dendrites play in transmission at chemical synapses?
Dendrites are the beginning of action potentials as they are formed and then propagate through a neuron. At the synapse, the dendrites receive the incoming signal from neurotransmitters released at the terminal of the previous neuron.
What is the function of the counter ion in a complex?
the role of counter ion in a reaction is it make the complex electrically neutral.
Explain how a catalyst aids chemical reaction to take place and identify the subsequent chemical changes in the reaction?
The role of a catalyst is to quicken the chemical reaction . On reacting, it subsequently appears as a product in the next step of the reaction.
What is the chemical reaction role of energy?
energy is released or absorbed.
What best explains the role of a catalyst in a chemical reaction?
The phenomenon which best explains the role of catalyst in a reaction is that the catalyst lowers the Energy of Activation :)
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 the role of enzyme in cells?
enzyme sped up the chemical reaction
The role of a catalyst?
A catalyst is a substance which alters the rate of a chemical reaction but is chemically unchanged at the end of the reaction. basically it increases or decreases the speed of a chemical or biological reaction, but it does not get itself involved in the reaction. hoped this helped (:
What is the role of the acetic anhydride in this reaction in the synthesis of acetanilide?
The chemical reaction is:C6H5NH2 + (CH3CO)2O → C6H5NHCOCH3 + CH3COOH
Which describes the role of sunlight in chemical reactions?
photosynthesis ------------------------------------------- generically a "photochemical" reaction.
Which best describes the role of enzymes in chemical reactions?
to increase the reaction rate
What role do catalysts play in chemical reactions?
A catalyst is a chemical species that alters the rate of a chemical reaction without undergoing any type of change. Such catalysts that slow down a reaction are called negative catalysts or poison.
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.
