    Among  molecule the energy required to break the first N-H bond and other N-H bond is not same" is true.

    The reason for this is -

    • Dissociation energy for the bond of  that is of N-H and  species gets decreased in its value.
    • This means that the breaking of first N-H bond of ammonia molecule during dissociation requires more energy or the highest energy among all the further dissociation.
