Why Is Exothermic Enthalpy Change Always Negative? Have you ever wondered why certain chemical reactions release heat and how scientists measure this energy change? In this informative video, we’ll explain the concept of enthalpy change and why it is always shown as a negative value during exothermic reactions. We’ll start by defining what enthalpy change (Delta H) is and how it relates to heat transfer at constant pressure. You’ll learn why energy is released when bonds form in the products and how this energy release results in a decrease in the system’s overall energy. We’ll discuss the molecular processes behind bond formation and breaking, and how the balance of these energies determines whether a reaction is exothermic. Additionally, we’ll explore real-world examples like burning methane or wood, which always have negative Delta H values because they release heat into their surroundings. Understanding why enthalpy change is negative helps explain why certain reactions are spontaneous and energetically favorable. Whether you’re studying chemistry or just curious about how energy flows during chemical reactions, this video provides clear explanations to deepen your understanding.
