entropy at equilibrium

[SarahCoufal_1k]

Why is entropy a maximum at equilibrium. ( looking at the equation deltaS= q/T)

[Isha_Maniyar_Dis2E]

Entropy is a maximum at equilibrium because deltaS(system) = -deltaS(surroundings). At equilibrium, one side will gain all the possible entropy, while the other will lose it.

Hope this helped!

In equilibrium, the entropy of the system cannot increase (because it is already at a maximum) and it cannot decrease (because that would violate the second law of thermodynamics).

[Tiffany_Chen 2K]

At equilibrium, deltaS(total)=0. Thus, deltaS(sys) will have the opposite relationship to deltaS(surr). Any entropy change will be the only entropy change to the system (as deltaS(surr) will only reflect the exact opposite of deltaS(sys)).
