Which reaction has the most positive entropy change understandard conditions?

Which reaction has the greatest positive change in entropy, DeltaS ?

DeltaG is the net energy available to do useful work and is a measure of free energy. If a reaction has positive enthalpy change and positive entropy change, under what conditions will the reaction be spontaneous?

DeltaG is the net energy available to do useful work and is a measure of free energy. If a reaction has positive enthalpy change and positive entropy change, under what conditions will the reaction be spontaneous?

DeltaG is net energy available to do useful work and is thus a measure of " free energy".Show mathematically that DeltaG is a measure of free energy.Find the unit of DeltaG .If a reaction has positive enthalpy change and positive entropy change, under what condition will the reaction be spontaneous?
