The value of Δ H ° involved in formation of CH 3 Cl and HCl should be calculated. Concept introduction: Thermodynamics is a study of energy transfers that can be done by either heat or work. The energy transferred through work involves force. When work is positive then system gains energy while when work is negative then system loses energy. Heat is not a state function and therefore change in enthalpy of reaction ( Δ H ° rxn ) has been introduced. The formula that Δ H ° from bond dissociation of reactants and products is as follows: Δ H ° = Sum of D H ° of bonds broken − Sum of D H ° of bonds formed

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.
