Expert Solution

Step 1: Given information:

A balanced chemical equation for the reaction of ammonia, NH₃ with oxygen is given as follows:

$4 space N H subscript 3 space left parenthesis g right parenthesis space plus space 7 O subscript 2 space left parenthesis g right parenthesis space rightwards arrow space 4 N O subscript 2 space left parenthesis g right parenthesis space plus space 6 H subscript 2 O space left parenthesis g right parenthesis$

The change in enthalpy of reaction $increment H subscript r x n space end subscript$ is given as $negative 905 space k J divided by m o l$ .

The bond energies in kJ/mol for O-H, N-H, and O=O bonds are given as follows:

Bond	Bond Energy (kJ/mol)
O-H	464
N-H	389
O=O	498

We have to determine the bond energy of the N-O bond of NO₂.
