Ingrid hess law
WebbIn short, the Hess’s law is based on the fact that enthalpy is a state function, and therefore, Δ Hrxn is the same whether the reaction takes place in one step or in a series of steps. For example, the enthalpy change for the reaction 2A + B → 2D can be calculated using the enthalpies of the two reference reactions: WebbHess's law allows the enthalpy change (Δ H) for a reaction to be calculated even when it cannot be measured directly. This is accomplished by performing basic algebraic operations based on the chemical equations of reactions using previously determined values for the enthalpies of formation.
