Thanks for asking us a question in Ask the Expert section of TopperLearning.com.
The bond dissociation enthalpy is the energy needed to break one mole of the bond to give separated atoms - everything being in the gas state. As it takes energy to break a bond, dissociation enthalpies are always positive numbers.
