Verified by Toppr. Hess's law of constant heat summation: The law states that the change in enthalpy for a reaction is the same whether the reaction takes place in one or a series of steps. The Hess's law can also be stated as the enthalpy change for a chemical reaction is the same regardless of the path by which the reaction occurs. Web4. Hess’s Law of Heat Summation Hess’s Law states that the total enthalpy change for a reaction is the same whether the reaction occurs in one or several steps. This law is based on the fact that since H is a state function, ∆H is independent of the path followed and depends only on the initial and final states. This is illustrated metasphere case management
