The statement that is correct concerning Hess's law is D. Hess' Law of Constant Heat Summation expresses that paying little respect to the numerous stages or ventures of a response, the aggregate enthalpy change for the response is the whole of all progressions. This law is an indication that enthalpy is a state work.
