    Well what makes a reaction spontaneous or not? It all depends on the Gibb's free energy. G=H-TS When G < 0 it's spontaneous, and when G > 0 It's not spontaneous, that's by definition in thermodynamics but also it makes sense. The main thing to be aware of is that spontaneous doesn't mean "fast" it just means it happens on its own, however this can mean it takes super super slowly like years, like diamonds turning into graphite is spontaneous but we can't observe it over small time scales... That being said, what is this equation? Well remember, ,exothermic and endothermic are actually special cases of what H can be, so the limiting cases are going to be when T and S combined with that particular choice of H will flip the sign on G. Kinda confusing I know, so give it some time to sink in.

    My understanding of reversible |dw:1444103353251:dw| Delta G has to do with like energy that's available to do work, I think that's where the "free comes from" would like to see someone derive it though.

    Wait this is multiple choice? I was thinking you were looking for the specific cases for each.
