ΔStotal

Hi,

I'm pretty sure that S> 0 correct, but can the change in entropy or does ΔStot have to be positive? I'm a little confused, thank you!

ΔStot for a system depends on the overall changes occurring in the system and its surroundings. If the entropy of the system increases but the entropy of the surroundings decreases by a greater amount the total change in entropy can still be positive. If both the system and the surroundings experience an increase in entropy, total entropy will be positive.

I think that the second law states that is always greater than 0 since total entropy refers to the entire universe.

DeltaS total could be equal to zero if temperature is equal to zero. This also means that delta G is equal to equillbrium.
