WebOct 11, 2024 · 7.12 Recall that the breaking of bonds is endothermic and the making of bonds is exothermic. WebThe first step is the endothermic step of breaking the reactant bonds and the second is the exothermic step of making the product bonds. The energy change of the reaction can be viewed as the sum of these two steps, and results in two possibilities, The exothermic step (2) is greater than the endothermic step (1) and the reaction is exothermic.

WebCreating new bonds releases it. The enthalpy of a reaction is equal to the energy required to break the bonds between reactants minus the energy released by the formation of new bonds in the products. So, if a reaction releases more energy than it absorbs, the reaction is exothermic and enthalpy will be negative.
