The total entropy change of the universe is calculated using the following thermodynamic principles:
ΔSuniv = ΔSsys + ΔSsurr
Where the entropy change of the surroundings is determined by the heat exchanged with the system:
ΔSsurr = -ΔHsys / T
Interpretation:
- ΔSuniv > 0: Spontaneous process
- ΔSuniv < 0: Non-spontaneous process
- ΔSuniv = 0: Equilibrium
