The transition state
In chemistry, 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. It is often marked with the double dagger ‡ symbol. As an example, the transition state shown below occurs during the SN2 reactio… WebNov 3, 2010 · A transition state is a very short-lived configuration of atoms at a local energy maximum in a reaction-energy diagram (aka reaction coordinate). A transition state has partial bonds, an extremely short …

WebJan 25, 2024 · Also during the transition from the solid to the liquid state, a sudden change of the binding energy occurs. While the molecules in the solid state are firmly bound to a specific location due to the great binding forces, the molecules in the liquid state can move relatively freely due to the weak binding forces.
