According to 'the 2nd law of thermodynamic', as you know, all reaction is moved to the direction of increasing entropy(S).
But we use Gibbs free energy(G)more frequently than entropy(S) to know directions of reactions or equilibrium states.
Why???
Why they use "Gibbs Energy(G)" instead of "Entropy(S)"?

No? Do you mean exothermic reactions?
If you look to nature und technology, you' ll find exothermic and endothermic reactions and reactions with increasing or decreasing entropy.
If you look for stability, a state with lower free enthalpy is more stable than a state with a higher one.

I got it! Thanks Michael.
