Question

The terms bond enthalpy and bond dissociation enthalpy stand for one and the same thing. If true enter 1 else 0

Answer 1

Hint:In the given question we will discuss about the bond enthalpy and bond dissociation enthalpy and segregate between the bond enthalpy and the bond dissociation enthalpy. As both of them are used in terms of bond. Both of them require energy.

Complete answer:
We know that the bond energy term is the energy essentially required to break a bond, or somewhat a mole of these bonds. So, the term bond enthalpy means bond energy and it is defined as the amount of bond strength in a chemical bond. So, Bond energy is an average value.

As the bond dissociation enthalpy is that required energy which needs to break the bond between two atoms of a molecule within gaseous state. The term enthalpy of formation of bond is stated as the quantity of heat evolved when a bond is formed between two free atoms in a gaseous state which form a molecular product within a gaseous state.

Basically, Bond dissociation energy will provide the energy needed to form free radicals from the atoms which formed that particular bond. Thus, the term bond enthalpy and bond dissociation enthalpy do not stand for one and the same thing.

Hence, the correct answer is ‘0’

Note:Bond dissociation enthalpy or enthalpy of formation of bond whereas the Bond dissociation energy is stated as the standard enthalpy change which is compulsory to break a chemical bond. Bond energy offers the energy needed to form the atoms which are the starting substantial for formation of bond.
