Gibbs Free Energy quantifies the tradeoff between what two important thermodynamical values, and was used to explain why there is an equilibrium vacancy rate. Briefly explain what these two values represent in the context of a solid material.

Solution

SOLUTION:-

Gibbs free energy (G) is the amount of energy remaining after a chemical reaction occurs. The change in free energy (G) is equal to change in enthalpy(H) minus temperature multiplied by the change in entropy(S)

G = H - T.(S)

These potentials or values --> Enthalpy (H) and Entropy (S) are the two important thermodynamic values that are related by Gibbs free energy.

- In case of solid material, entropy represents the amount of energy that spreads within the solid material to convert it into a liquid at a particular temperature.

-In case of solid material, enthalpy is the internal energy of the solid and is temperature dependant.
