Question

Write short note activeted complex with example

Answer 1

Answer:

Explanation:

A new bond between H and F must also form to make HF. The reactant bonds break at the same time that the product bonds form. This is called the activated complex or transition state. ... In this example, the final product is HF and it has a lower energy than the reactants.

Answer 2

Explanation:

In chemistry an activated complex is defined by the International Union of Pure and Applied Chemistry (IUPAC) as "that assembly of atoms which corresponds to an arbitrary infinitesimally small region at or near the col (saddle point) of a potential energy surface".[1] In other words, it refers to a collection of intermediate structures in a chemical reaction that persist while bonds are breaking and new bonds are forming. It therefore represents not one defined state, but rather a range of transient configurations that a collection of atoms passes through in between clearly defined products and reactants.

It is the subject of transition state theory - also known as activated complex theory - which studies the kinetics of reactions that pass through a defined intermediate state with standard Gibbs energy of formation ΔG°‡.[2] The state represented by the double dagger symbol is known as the transition state and represents the exact configuration that has an equal probability of forming either the reactants or products of the given reaction.[3]
