Chapter 2.1, Problem 2.6E

(a)

Interpretation Introduction

Interpretation: The value of free energy change for decomposition of chloroethane is to be calculated at 25 °C .

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.

Changes in entropy are determined by relative extent of energy dispersal in substrates materials compared products. The higher the magnitude of energy dispersal, the higher is positive ΔS° .

(b)

Interpretation Introduction

Interpretation: The value of free energy change for decomposition of chloroethane is to be calculated at 500 °C .

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.

Changes in entropy are determined by relative extent of energy dispersal in substrates materials compared products. The higher the magnitude of energy dispersal, the higher is positive ΔS° .
