When is the bond enthalpy equal to the bond dissociation enthalpy ?
Asked by pratikbharadia | 28th Nov, 2009, 02:00: PM
Bond dissociation enthalpy is the amount of energy required to break one mole of bond of a particular type between the atoms in the gaseous state. It is for a bond between atoms of a gaseous homonuclear molecule.
However, in the case of polyatomic molecules, which contain more than one bond of the same type, mean value of the dissociation enthalpies is taken. The average bond dissociation enthalpies required to dissociate bond in a substance is called bond enthalpy.
