Chapter 2, Problem 32P

(a)

Interpretation Introduction

Interpretation: The value of ΔH° of below reactions is to be calculated from the bond strength data.

  ORGANIC CHEMISTRY (LL)-PACKAGE, Chapter 2, Problem 32P , additional homework tip  1

Concept introduction: The formula to calculate ΔH° from bond dissociation of reactants and products is as follows:

  ΔH°=Sum of DH° of bonds brokenSum of DH° of bonds formed

(b)

Interpretation Introduction

Interpretation: The value of ΔS° should be assigned for each below reaction and reason should be briefly explained.

  ORGANIC CHEMISTRY (LL)-PACKAGE, Chapter 2, Problem 32P , additional homework tip  2

Concept introduction: The formula that determines spontaneity of the reaction is,

  ΔG°=ΔH°TΔS°

Where,

  • ΔS°denotes entropy change of reaction.
  • ΔH°denotes enthalpy change of reaction.
  • Tdenotes temperature.
  • ΔG°denotes standard Gibbs energy.

(c)

Interpretation Introduction

Interpretation: The value of ΔG° is to be calculated for each reaction at 25 °C and 600 °C also, whether reactions are thermodynamically favorable at 25 °C and 600 °C should be determined.

Concept introduction: The formula that determines spontaneity of the reaction is,

  ΔG°=ΔH°TΔS°

Where,

  • ΔS°denotes entropy change of reaction.
  • ΔH°denotes enthalpy change of reaction.
  • Tdenotes temperature.
  • ΔG°denotes standard Gibbs energy.
