From the values of ΔH and ΔS, predict which of the following reactions would be spontaneous at 28°C: reaction A: ΔH = 10.5 kJ/mol, ΔS = 30.0 J/K.mol; a) spontaneous b) nonspontaneous c) impossible to tell reaction B: ΔH = 1.8 kJ/mol, ΔS = -13 J/K.mol; a) spontaneous b) nonspontaneous c) impossible to tell If either of the reaction is nonspontaneous, can it(they) become spontaneous? If either of the reactions in nonspontaneous but can become spontaneous, at what temperature might it become spontaneous?
