Delta S(tot)

Postby Jared Smith 1E » Wed Feb 14, 2018 11:40 am

Can someone please explain what the difference between delta S, delta S (surroundings), and delta S (tot) is? Also, how do these relate to each other when calculating them?

These three terms are related by deltaStotal=deltaSsystem+deltaSsurroundings.

Also, specifically for in a reversible system, deltaS(tot) is equal to 0, so deltaS(sys) = -deltaS(surr)

Also, when the reaction is irreversible, Ssurroundings = 0.

I don't think that's true.

Oh, I have that in my notes from a TA-led review session... maybe I misunderstood what he was saying then.
