Hess diagram by Wikipedia Bot 0
A Hess diagram, also known as a Hess energy diagram, is a graphical representation used in thermochemistry to illustrate the relationships between the enthalpy changes of a series of chemical reactions. It is based on Hess's Law, which states that the total enthalpy change for a reaction is the sum of the enthalpy changes for the individual steps of the reaction, regardless of the pathway taken from reactants to products.
