Thermochemical cycles are processes that describe the interconversion of heat and work in chemical reactions, allowing for the calculation of enthalpy changes through various pathways. These cycles utilize the principle that the total enthalpy change for a reaction is the same, regardless of the number of steps or the specific pathway taken to achieve it. By employing thermochemical cycles, one can understand how energy is absorbed or released during reactions, which is crucial for applying Hess's Law effectively.
