This review study involves explanation about intermediate. any reacting species which is no longer a transition state. KEYWORDS: Reaction, Energy , Rate, Cation INTRODUCTION The easiest way to understand the difference between a transition state and an intermediate is to use what is commonly called a reaction (energy) diagram, like the one below. When the S P reaction is catalyzed by an enzyme, the ES and EP complexes are intermediates (Eqn 8-1); they occupy valleys in the reaction coordinate diagram (.Fig. 8-4). When several steps occur in a reaction, the overall rate is determined by the step (or steps) with the highest activation energy; this is called the rate-limiting step. (NOTE: In practice, an S N 1 reaction like this is difficult to perform in the lab under such strongly basic conditions with an alkyl halide, but it provides a nice, simple case with which to illustrate the kinetics.). Because there are two steps involved, there are also two transition states and two activation energies to consider, as well as the carbocation intermediate.

A reaction coordinate diagram may also have one or more transient intermediates which are shown by high energy wells connected via a transition state peak. Any chemical structure that lasts longer than the time for typical bond vibrations (10 −13 - 10 −14 s) can be considered as intermediate.

Drag the appropriate labels to their respective targets. :4 , Intermediates, Transition states, Potential energy diagrams and Hammond's postulate Fig.7: Reaction coordinate diagram showing TS There may be more than one transition state for a reaction, generally for multi-step reactions. The local minima represent reactive intermediates and the local maxima are TSs (figure 8). The Transition State. The transition state is the higher energy point between two minima along the reaction coordinate. Each step in a mechanism will have a transition state. The transition states are often very difficult to identify and during a reaction the molecules exist in this state for essentially zero time. Transition States vs. Intermediates! A transition state is an unstable species! (it has no measurable lifetime)! Reaction Coordinate! An intermediate has a measureable lifetime! (it can be isolated in theory)!

Transition State Theory Wikipedia

Transition state theory (TST) describes a hypothetical "transition state" that occurs in the space between the reactants and the products in a chemical reaction. The species that is formed during the transition state is known as the activated complex. TST is used to describe how a chemical reaction occurs, and it is based upon collision theory.
