Break bonds negative

WebMultiple Choice When DH" is negative, more energy is needed to break bonds than is released in forming bonds. When DH" is positive, more energy is released in forming bonds than is needed to break bonds, Bond dissociation energies decrease down a column of the periodic table. Bond dissociation energies increase down WebGenerally, a positive change in enthalpy is required to break a bond, while a negative change in enthalpy is accompanied by the formation of a bond. In other words, breaking a bond is an endothermic process, while the formation of bonds is exothermic. Bond Enthalpy or Dissociation Energy
