The transition state of a chemical reaction is a particular configuration along the reaction coordinate. It is defined as the state corresponding to the highest potential energy along this reaction coordinate. At this point, assuming a perfectly irreversible reaction, colliding reactant molecules always go on to form products. It is often marked with the double dagger ‡ symbol.
As an example, the transition state shown below occurs during the SN2 reaction of bromoethane with a hydroxyl anion:
The activated complex of a reaction can refer to either the transition state or to other states along the reaction coordinate between reactants and products, especially those close to the transition state.
History of concept
The concept of a transition state has been important in many theories of the rates at which chemical reactions occur. This started with the transition state theory (also referred to as the activated complex theory), which was first developed around 1935 by Eyring, Evans and Polanyi, and introduced basic concepts in chemical kinetics that are still used today.
What ARE transition states and intermediates? And why are they SO important in chemistry? In this video, we explore the science of transition state theory to see how catalysts change the activation energy of the rate determining step and make the whole reaction faster.

transition states in chemical reactions

Transition states correspond to energy peaks in a reaction coordinate. Although they cannot be observed, the structure of transition states can be inferred from the structures of starting materials, intermediates, and products on the same curve. Speculative structures of transition states are characterized by partial bonds and partial charges that reflect the changing state of atoms during the reaction step. All chemical reactions have transition states.
