Expert Solution
Step 1

 

  • Gibbs free energy is a measure of enthalpy taking entropy into account.
  • It allows us to relate the two factors at a given temperature to find if the reaction is spontaneous.
  • If Gibbs is negative, the reaction will occur and if positive it will not happen (∆G =∆H-T∆S).
  • The change in Gibbs free energy is related to the emf of a redox reaction by the equation ∆G=-nFE.
