In an exothermic chemical reaction, how does the total enthalpy of the products compare to the total — Thermodynamics and Thermochemistry Chemistry Question

💡 Solution & Explanation

In an exothermic reaction ($\Delta H < 0$), heat is released to the surroundings because the system drops to a lower energy state. Products with lower enthalpy sit at a deeper energy well, making them thermodynamically more stable than the reactants.
