Answer:
Hess's Law of Constant Heat Summation (or just Hess's Law) states that regardless of the multiple stages or steps of a reaction, the total enthalpy change for the reaction is the sum of all changes. This law is a manifestation that enthalpy is a state function.
Hess's law states that no matter the multiple steps or intermediates in a reaction, the total enthalpy change is equal to the sum of each individual reaction. It is also known as the conservation of energy law. ... Or, we can determine the enthalpy change for A+B=AB and AB+C=ABC and then add these two together.
