$(a-b)$

Vedclass · Answer

(B) The potential energy of two $H$ atoms at an infinite distance is represented by $a$.The potential energy of the $H_2$ molecule at the equilibrium bond length is represented by $b$.The bond energy is defined as the energy required to break the bond,which is the difference between the energy of the separated atoms and the energy of the bonded molecule.Therefore,the bond energy is $(a-b)$.

The potential energy $(y)$ curve for $H_2$ formation as a function of internuclear distance $(x)$ of the $H$ atoms is shown below.
The bond energy of $H_2$ is
