Answered by Arslankincsem

As per the Hess’s law

“The amount of heat evolved or absorbed in a chemical change is the same whether the process takes place in one step or in several steps”.

This whole process is the first law of thermodynamics that is calculated for the transition, enthalpy of formation, bond energy, etc.
