The number of phases is the sum of these two quantities. For example, if you have an ethanol-water solution with a 20% ethanol content, then there …
WebApr 17, 2024 · The Gibbs energy helps us to summarize all this in a single quantity. It combines entropy and enthalpy changes in the system in a neat way that tells us about the maximum work. In the absence of work, it also tells whether the process will happen in that direction or not. Disclaimer for those that have a physical chemistry background Josiah Willard Gibbs was an American scientist who made significant theoretical contributions to physics, chemistry, and mathematics. His work on the applications of thermodynamics was instrumental in transforming physical chemistry into a rigorous inductive science. Together with James Clerk Maxwell and Ludwig Boltzmann, he created statistical mechanics (a term that he coined)…
