WebMar 16, 2024 · Hello! In terms of endothermic vs exothermic reactions, I usually think of the change of enthalpy throughout the reaction. This includes exothermic equations releasing energy to end up with a negative enthalpy and endothermic equations obtaining energy to end up with a positive enthalpy. Energy is often required to break bonds as well. WebMay 11, 2016 · So, finally, $$\Delta H=Q$$ So, for a process carried out at constant pressure, if the heat added to the system is positive (endothermic), $\Delta H$ is positive and if the heat added to the system is negative (exothermic, heat removed from system), $\Delta H$ is negative. pnc bank rockfordWebJun 19, 2024 · This excess energy is released as heat, so the reaction is exothermic. Hence, we can re-write the reaction with the heat released (111 kcal) on the product side of the equation, as follows: We can also re-write the reaction equation with the ΔH information (see below). Note that an exothermic reaction has a negative ΔH value. pnc bank roma tx
