Thermodynamic Property Exothermic Process Endothermic Process Delta H (Enthalpy Change) Negative (ΔH < 0) Positive (ΔH > 0) Energy Flow System to Surroundings Surroundings to System Temperature of Surroundings Increases (Feels Hot) Decreases (Feels Cold) Real-World Examples and Observational Evidence The theoretical definition becomes clear when observing common phenomena. Differentiating Exothermic and Endothermic Processes To solidify the concept, it is helpful to contrast the scenario where delta H is negative with the alternative.
Understanding Exothermic Favorability When Delta H is Negative
To directly answer the core question: when delta H is negative, the process is exothermic. These real-world instances validate the rule that a negative enthalpy change is synonymous with an exothermic transition.
This surplus energy is expelled from the system, increasing the kinetic energy of the surroundings, which manifests as a temperature rise. When delta H is positive, the reaction is endothermic, meaning the system absorbs heat.
Understanding Exothermic Favorability When Delta H is Negative
In an exothermic reaction, the energy released during the formation of the product bonds exceeds the energy required to break the original reactant bonds. When analyzing thermodynamic processes, one of the most frequent points of confusion concerns the sign of delta H and what it implies for the energy flow within a system.
