Reaction enthalpy (ΔHrxn) represents the heat absorbed or released during a chemical reaction at constant pressure. It can be determined experimentally (calorimetry) or calculated from known enthalpies of formation or bond energies. A negative ΔHrxn indicates an exothermic process, while a positive value indicates an endothermic process. Reaction enthalpy is crucial in process design and understanding energy requirements.
