Interpretation:
More stable polymorph of sulfur has to be determined using the given standard Gibbs energy of formations of rhobic and monoclinic sulfur.
Concept introduction:
Free energy (Gibbs free energy) is the term that is used to explain the total energy content in a
Where,
Gibb’s energy is an important factor which greatly affect the thermodynamic stability of a molecule or compound.
For example: when state A is said to be more thermodynamically stable than state B of a chemical system, if the Gibbs energy of the change from A to B is positive.
The stable state of the chemical system is taken as its reference state.
The substance with lower molar Gibbs energy is more stable.
