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.

ΔH°=Sum of DH° of bonds broken−Sum of DH° of bonds formed

Answer 13

(d)

Interpretation Introduction

Interpretation: The value of ΔH° involved in formation of HI 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 the system gains energy while when work is negative then the system loses energy.
