From the given standard enthalpies, the N-H bond energy needs to be determined. Concept Introduction: For a reaction, the change in enthalpy can be calculated from bond dissociation energy as follows: Δ H = ∑ B . E ( Reactant ) − ∑ B . E ( Product ) That is the difference of total energy of bond broken and total energy of bond formed. Also, from standard enthalpy of formation, the change in enthalpy of reaction is calculated as follows: Δ H = ∑ Δ H ( Product ) − ∑ Δ H ( Reactant )

Answer 1

Question

Formula Formula Bond dissociation energy (BDE) is the energy required to break a bond, making it an endothermic process. BDE is calculated for a particular bond and therefore consists of fragments such as radicals since it undergoes homolytic bond cleavage. For the homolysis of a X-Y molecule, the energy of bond dissociation is calculated as the difference in the total enthalpy of formation for the reactants and products. X-Y → X + Y BDE = Δ H f X + Δ H f Y – Δ H f X-Y where, ΔHf is the heat of formation.
