Question

Heat of atomisation of NH₃ and N₂H₄ are x kcalmol⁻¹ and y kcalmol⁻¹ respectively. What will be average bond energy of N−N

?

Answer 1

The average bond energy of N-N can be calculated using the heat of atomization values for NH3 and N2H4. The formula to calculate the bond energy of N-N is (2x + 4y)/3 kcal/mol.

Step-by-step explanation:

The average bond energy of N-N can be calculated using the heat of atomization values for NH₃ and N₂H₄:

Let's assume the heat of atomization of NH₃ is x kcal/mol and the heat of atomization of N₂H₄ is y kcal/mol.

The bond energy of N-N, in kcal/mol, can be calculated as:

Bond Energy of N-N = (2x + 4y)/3

Therefore, the average bond energy of N-N is (2x + 4y)/3 kcal/mol.
