Solution:
potential energy of two H atoms at infinite distance = a
Potential energy of two H atoms at distance equal to bond length = b
BE = (b – a)
The potential energy (y) curve for H2 formation as a function of inter nuclear distance (x) of the H atoms is shown below.The bond energy of H2 is
The potential energy (y) curve for formation as a function of inter nuclear distance (x) of the H atoms is shown below.
The bond energy of is
