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.

3) An empirical function that might be used to represent the molecular energy is E=0 一 B where A and B are positive constants. Find A and B in terms of the equilibrium separation Req and the dissociation energy Eo.

Is this correct?

H2 has equilibrium bond length of 0.751 Å and bond dissociation energy of 432 kJ mol21 , whereas F2 has equilibrium bond length of 1.417 Å and bond dissociation energy of 155 kJ mol21. On the same graph show qualitativesketches of the effective potential energy curve Veff for an H2 and an F2 molecule. In your solution, show the conversion from kJ mol21 to the energy of a single molecule.
