#### Answer:

See below

#### Explanation:

Enthalpy (

Entropy (

Therefore, there is no direct relationship between entropy and enthalpy. However, the free energy (

where at constant temperature, the change on free energy is defined as:

Therefore, the free energy expression provides a relationship between enthalpy and entropy.

Thus, for a system at equilibrium,
