Activated Complex

A molecular assembly formed from the collision of energetic particles which corresponds to a transition (intermediate) state of a chemical reaction and gives rise to intermediates or end products.

The activated state is less solvated than the reactants which restricts the motion of activated complex. The Gibbs free energy change of activation (IG*) was found to be highest in aqueous isopropanol and lowest in water showed the formation of activated state is more favorable in water than in methanol, ethanol and isopropanol.
A constitutively activated complex (CReP:PP1c) dephosphorylates eIF2[alpha]-P under basal conditions.
Moreover, the transition state theory and KAS dynamics model were also used to investigate the energy triplet of the activated complex in the combustion processes.
It should be possible for AH and CHS in the chromosphere to form an activated complex, CHS + AH [right arrow] [CHS-HA.sup.*].
Effect of Dielectric Constant and Calculation of the Size of the Activated Complex. In order to find out the effect of the dielectric constant of the medium on the rate of the reaction, the reaction was studied at different dielectric constants (D) of the medium with constant concentrations of all other reactants and at a constant temperature.
Assume that there is an energy barrier (i.e., transition state) during the reaction between nanoparticle A and another reactant B (gas) and the intermediate product corresponding to the transition state is the activated complex [C.sup.[double dagger]] (denoted by [sup.[double dagger]]).
For the forward reaction between JCO and methanol, the reaction should acquire the activation energy level before the reactants can form the activated complex.

Activated complexes do not normally exist long enough to have an opportunity to absorb microwave energy, although there are a number of stabilized intermediates, resident stabilized intermediates, and other intermediates that are much longer lived.
