The standard enthalpy of formation of N H 3 ​ is 4 6 . 0 kJ/mol. If the enthalpy of formation of H 2 ​ from its atoms is − 4 3 6 kJ/mol and that of N 2 ​ is − 7 1 2 kJ/mol, the average bond enthalpy of N − H bond in N H 3 ​ is: A − 1 1 0 2 kJ/mol B − 9 6 4 kJ/mol C + 3 5 2 kJ/mol D + 1 0 5 6 kJ/mol

The standard enthalpy of formation of NH3​ is 46.0 kJ/mol. If the enthalpy of formation of H2​ from its atoms is −436 kJ/mol and that of N2​ is −712 kJ/mol, the average bond enthalpy of N−H bond in NH3​ is:

A

−1102 kJ/mol

B

−964 kJ/mol

C

+352 kJ/mol

D

+1056 kJ/mol
