Strongest bonds specific heat
WebJul 31, 2024 · Because the bonds in the products are stronger than those in the reactants, the reaction releases more energy than it consumes: ΔH = ∑Dbondsbroken − ∑Dbondsformed = [DH − H + DCl − Cl] − 2DH − Cl = [436 + 243] − 2(432) = − 185kJ This excess energy is released as heat, so the reaction is exothermic. WebOct 27, 2024 · Because the bonds in the products are stronger than those in the reactants, the reaction releases more energy than it consumes: ΔH = ƩDbonds broken − ƩDbonds formed ΔH = [DH−H + DCl−Cl] − 2DH−Cl = [436 + 243] − 2(432) = −185kJ This excess …
