Entropy, S
The molecular weight is in direct proportion with the increase of entropy at the same phase
Example: Entropy (NaCl) > Entropy (Na)
Between the increase in entropy in one process and the decrease in entropy in another, the increase in entropy has more dominant
Spontaneous reactions proceed to lower energy (ΔH) or higher disorder (ΔS)
Example: Entropy (H2O solid) < Entropy (H2O liquid) < Entropy (H2O gas)

The phase change process, ΔS(sys)

-
-
-
The phase change process is the entropy change by the reversible addition of heat between 2 states at a constant temperature

State function & Work
-
State function has 01 any value that can't measure, and that value depends only on the initial and final states of the system
Example: ΔE, ΔH, ΔS and ΔG
-
Gibbs Free Energy, ΔG
The Gibbs Free Energy of the reactants
=> decreasing =>
The minimum at the equilibrium
=> increasing =>
The Gibbs Free Energy of the products
-
Standard free energy of formation, ΔG°(f)
