Enthalpy change for a single reaction (Hess' law)

Formula

Enthalpy change for a single reaction (Hess' law) formula
DeltaHreaction
enthalpy change for a reaction
DeltaHfproducts
total heat of formation of the products
DeltaHfreactants
total heat of formation of the reactants

Formula description

Hess`s law states that the energy change for any chemical or physical process is path independent, only the initial and final states being of importance. This path independence is true for all state functions. And the enthalpy changes are additive.
