WebThe heat capacity, vapor pressure, heats of fusion and vaporization. The third law of thermodynamics and orientation equilibrium in the solid, J. Am. Chem. Soc., 1939, 61, 2366-2370. Stephenson and Malanowski, 1987 Webmore. With Hess's Law though, it works two ways: 1. You use the molar enthalpies of the products and reactions with the number of molecules in the balanced equation to find the change in enthalpy of the reaction. That's what you were thinking of- subtracting the change of the products from the change of the reactants. 2. WebHess's law is a fundamental principle in thermodynamics which states that the enthalpy change of a chemical reaction is independent of the pathway between the initial and final states. In other words, the enthalpy change of a reaction is the same whether it takes place in one step or in a series of steps. cva as cause of death
