Question

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 :, ( b - a ), ( c - a ) 2, ( b - a ) 2, ( c - a )

MARKS App · Accepted Answer

As per the given curve bond energy is the amount of energy is released during the bond formation is i.e. = Final - initial So, Potential energy of two H atoms at infinite distance (initial) $=\mathrm{a}$ and Potential energy of two H atoms at distance equal to bond length (final) $=\mathrm{b}$ Then, $\text {B.E. }=(b-a)$
