This statement is a restatement of Hess's Law. Hess's Law states that the total enthalpy change of a reaction is the sum of the enthalpy changes of the individual steps in the reaction pathway, regardless of the number of steps or the specific pathway taken. This principle is based on the first law of thermodynamics, which emphasizes that energy cannot be created or destroyed, only transformed.

Hess's Law allows chemists to calculate the enthalpy change of a reaction by using the enthalpy changes of other reactions that are known, making it invaluable for thermodynamic calculations. In practical terms, if you can break a reaction down into multiple steps and determine the ΔH for each step, you can simply add these quantities to find the overall enthalpy change, ΔHoverall. This makes it easier to analyze complex reactions that may not be straightforward to measure directly.
