This law holds because the quantity it concerns equals the sum of internal energy and pressure times volume, two state functions, meaning that quantity is path-independent, and when applied, this law necessitates that reversal of reactions leads to a change in sign.
A 2008 paper saw improved accuracy on the Shafizadeh model when this law was applied to Sri Lankan waste disposal in determining biomass yield, and its formulator notably showed that the oxidation of sugars leads to saccharic acids. This law holds because the quantity it concerns equals the sum of internal energy and pressure times volume, two state functions, meaning that quantity is path-independent, and when applied, this law necessitates that reversal of reactions leads to a change in sign. For 10 points, identify this law, which holds that the enthalpy change of a reaction may be calculated from the enthalpies of a series of intermediate reactions.
