Explanation / Answer

From the graph bond length of H2 is the distance between the two H atom when the potential energy is the minimum.
The potential energy is minimum when the distance between the two atoms 0.74 Ao.
Hence, the bond length of the H2 molecule is 0.74 Ao.

The bond strength is the energy corresponding to the bond length from th egraph. This is the energy required to dissociate the H2 molecule. The energy corresponding to the bond length is 436 kJ mol.
hence, the bond strength in the H2 molecule is 436 kJ/ mol.
