What exactly is Stot? Is this a combination of the change in entropy of surroundings minus the change in entropy of the system? Furthermore, how can you use Stot to determine spontaneity?

I believe deltaS total (aka S universe) is the deltaS surr plus deltaS sys. If deltaS total is positive, the process is spontaneous, if deltaS total is negative the reaction is non spontaneous, and if deltaS total is 0, the reaction is at equilibrium.
