Is a reaction that is exothermic and becomes more positionally random spontaneous or non spontaneous? What about less positionally random? Is there enough information to tell?
See this answer for the endothermic case.
Therefore, the Gibbs' free energy is:
#color(blue)(DeltaG) = DeltaH - TDeltaS#
#= (-) - (+)(+)#
#= (-) - (+)#
which if you recall, is negative for a spontaneous reaction.
So, an exothermic reaction with increased motion (more "positional randomness") is spontaneous at all temperatures.
Less "positionally random" implies less motion and thus
