Answer:

In a chemical reaction bonds are broken and formed. The enthalpies of reactions involving substances having covalent bonds are calculated by knowing the bond enthalpies of reactants and those in products. The calculations assume all the bonds of a given type are identical

Answer:

The value of the enthalpy change of a reaction can determine if the reaction is endothermic or exothermic. If the enthalpy change of reaction is negative, then the reaction is exothermic, meaning energy is released and stronger bonds are formed than the ones that are broken.

bond enthalpy is the enthalpy change when one mole of gaseous molecules each breaks a covalent bond to form two free radicals, averaged over a range of compounds
