Different entropy measures 4.37
What is the difference between ΔS and ΔStotal? And why is ΔStotal always greater than 0 in a spontaneous process if ΔS is necessarily positive in a spontaneous reaction?

Re: Different entropy measures 4.37
I think ΔStotal refers to the ΔS of both the system and the surroundings added up. The requirement for a process to be spontaneous is for ΔStotal to be positive, however ΔS does not have to be positive in order for the process to be spontaneous because the other ΔS of either the system or the surrounding can bring ΔStotal back up to being positive. I hope this helped!

Plus, in an equation ΔS usually refers to the system (the sys at the end is dropped).

Re: Different entropy measures 4.37
Delta S total is about the total entropy of the surroundings and the system and Delta S is just about the system you are referring to.
