It states that the enthalpy change of a reaction is independent of the pathway taken, thus allowing enthalpies of small reactions to be added together in order to find the net enthalpy of a process.
Its namesake observed that enthalpy is a state function, and thus that this law allows for the determination of enthalpy change by measuring the individual steps in a reaction rather than the reaction as a whole. It states that the enthalpy change of a reaction is independent of the pathway taken, thus allowing enthalpies of small reactions to be added together in order to find the net enthalpy of a process. FTP, name this law used to predict the enthalpy change of a chemical reaction.
