WebNow we need to calculate the bond energy between the products. For this reaction it is two moles of nitrogen to hydrogen single bonds. For this bond, each nitrogen is bond to three hydrogens so it is 6 bonds. 6 mol x N-H (400 kJ/mol) = 2400 kJ. 3. Finally, we will calculate the energy change. WebThis is really important. You have got to get this right, otherwise you won't get bond energy sums right. It is pretty obvious that to break a bond, you will have to put in energy. You …
