From the values of delta H and delta S, predict which of the following reactions would be spontaneous at 25*C:
Reaction A: delta H=10.5 kJ/mol, delta S=30J/K mol
Reaction B: delta H=1.8 kJ/mol, delta S=-13J/K mol
If any of the reactions is nonspontaneous at 25*C, at what temperature might it become spontaneous?
