Second Law of Thermodynamics
The
Second Law of Thermodynamics says that for a spontaneous process, the
total entropy of the system and the surroundings increases.
Put another way ... the entropy of the universe is always increasing. If a spontaneous process occurs, either the system became more disordered or the surroundings became more disordered ... and the increase in disorder of one is always greater than the increased organization of the other.

ΔStotal
> 0 for spontaneous processes
ΔS = 0 at equilibrium
ΔStotal < 0 for non-spontaneous processes
ΔS = 0 at equilibrium
ΔStotal < 0 for non-spontaneous processes
