In physical chemistry and thermodynamics, Hess's law of constant heat summation, also known simply as Hess's law, is a scientific law named after Germain Hess, a Swiss-born Russian chemist and physician who published it in 1840. The law states that the total enthalpy change during the complete course of a chemical reaction is independent of the sequence of steps taken.
