Energy diagram

Definition

An energy diagram is a graphical representation that shows the energy changes during a chemical reaction, illustrating the transition from reactants to products and highlighting intermediate states and activation energy. It helps in understanding the energetics and kinetics of a reaction, including whether it is exothermic or endothermic.

Related terms

Activation Energy:

The minimum amount of energy required for reactants to transform into products in a chemical reaction.

Transition State:

A high-energy, unstable arrangement of atoms that exists momentarily as reactants are converting into products during a chemical reaction.

Exothermic Reaction:

A chemical reaction that releases energy by light or heat, indicating that the total energy of the products is less than that of the reactants
