(a)
Interpretation: Whether the starting material or product is favored at equilibrium is to be predicted on the basis of the given value of
Concept introduction: The change in Gibbs free energy and enthalpy is represented by
The change in Gibbs free energy describes the spontaneity of the reaction, whereas the change in enthalpy describes the relative bond strength in the substance.
(b)
Interpretation: The starting material or product which is favored at equilibrium is to be identified.
