Entropy and Equilibrium

Postby Sean Reyes 1J » Sat Feb 09, 2019 6:54 pm

Hi, I was just looking at my lecture notes and I didn't really understand why entropy is a maximum at equilibrium? Thanks!

I believe it is because we are assuming that the reaction is isothermal and reversible, which is theoretically supposed to yield the highest enthalpy and entropy, so we apply entropy and enthalpy as maximums for such reactions

For an isolated system, when a system is at equilibrium, it has searched out all of the possible states/positions of atoms. In other words, an isolated system at equilibrium would have maximum degeneracy, which would result in the maximum entropy.
