Which of the following is the best definition of hess' law? a. heat evolved in a given process can be expressed as the sum of the heats of several processes that, when added, yield the process of interest. b. the enthalpy of a process is the difference between the enthalpy of the products and the enthalpy of the reactants. c. since enthalpy is a state function, it will be different if a reaction takes place in one step or a series of steps. d. at constant pressure the enthalpy change of a reaction is equal to the heat change of a reaction. e. heat is always released by the decomposition of 1 mole of a compound into its constitute elements.
