The relationship between the dissociation energy of N2 and N2+ is:

1. Dissociation energy of N2+ > dissociation energy of N2
2. Dissociation energy of N2 = dissociation energy of N2+
3. Dissociation energy of N2 > dissociation energy of N2+
4. Dissociation energy of N2 can either be lower or higher than the dissociation energy of N2+

Correct answer: Dissociation energy of N2 > dissociation energy of N2+

Solution

The dissociation energy of N2 is greater than that of N2+ because removing an electron from N2 weakens the bond by reducing the bond order from 3 to 2.5.
