Spontaneity
Processes are spontaneous when they result in an increase in disorder
The total energy of the universe is constant, but the entropy is increasing
Law of Thermodynamics
In any spontaneous process, there is always an increase in the entropy of the universe
Energy is conserved in the universe, but entropy is not
∆Suniv =
∆Suniv = ∆Ssys + ∆Ssurr
if ∆Suniv is positive then
entropy of the universe increases and the process is spontaneous in the direction written
if ∆Suniv is negative then
the process is spontaneous in the opposite direction
if ∆Suniv is 0 then
process has no tendency to occur, indicating that the system is at equilibrium
