Question

Give the difference between bond dissociation energy and bond energy with an example?

Please answer it

Answer 1

Answer:

bond dissociation energy is the minimum amount of energy required to break a bond and bond energy is the minimum amount of energy required to maintain or form a stable bond.

Answer 2

Answer:Bond energy is the average value of the gas-phase bond dissociation energies (usually at a temperature of 298 K) existing between the same types of atoms. However, bond energy and bond dissociation energy are not the same. Bond dissociation energy is the standard enthalpy change when a covalent bond (also termed as a molecular bond, is a chemical bond between two non-metal atoms, that involves the sharing of electron pairs between those atoms) is cleaved by homolysis (breakdown to equal pieces) to give fragments; which are usually radical species. Hence, the major difference between bond energy and bond dissociation energy is that bond energy is an average value whereas bond dissociation energy is a particular value for a particular bond.
