Thermochemistry is a branch of chemistry that qualitatively and quantitatively describes the energy changes that occur during chemical reactions. Energy is the capacity to do work. 5.2: The First Law of Thermodynamics The first law of thermodynamics states that the energy of the universe is constant. The change in the internal energy of a ...
We have realized that almost all of the aforementioned CO 2 super-emitters involve heat-induced or heat-driven thermochemical reactions, such as combustion, gasification, decomposition, calcination, reduction and sintering [].. These reactions are wildly popular in diversified industries, including energy, transportation, chemicals, metallurgy, mineral …
