The relationship between the dissociation energy of `N_2` and `N_2^+` is

Options

A. Dissociation energy of `N_(2)^(+)=` dissociation energy of `N_(2)`
B. Dissociation energy of `N_(2)=` dissociation energy of `N_(2)^(+)`
C. Dissociation energy of `N_(2)gt` dissociation energy of `N_(2)^(+)`
D. Dissociation energy of `N_(2)` can either be lower or higher than the dissociation energy of `N_(2)^(+)`

Answer

C

Explanation

Dissociation energy of any molecule depends upon its bond order. Bond order in `N_(2)` molecule is 3 while bond order in `Ni_(2)^(+)` is 2.5. Further we know that more the Bond order, more is the stability and more is the bond dissociation energy.
