8.) From the values of delta H and delta S, calculate delta G then predict whether the following reactions would be spontaneous or not at 25 C. a) Reaction A: delta H= 10.5 kJ/mol, and delta S = 30 J/K mol b) Reaction B: delta H=1.8 kJ/mol, and delta S = -113 J/K mol 9.) Calculate the delta G and K, for the following equilibrium reaction at 25 C: 2H2O(Ⓡ) <-> 2H2(g) + O2(8) delta Gran H2O(x) = -228.6 kJ/mol

From the values of delta H and delta S, predict which of the following reactions would be spontaneous at 26C: Reaction A: delta H = 10.5 kJ/mol, delta S = 30.0 J/K*mol Reaction B: delta H = 1.8 kJ/mol, delta S = -113 J/K*mol If either of the reactions is nonspontaneous, can it (they) become spontaneous? If either of the reactions is nonspontaneous but can become spontaneous, at what temperature might it become spontaneous? Please explain how to do this!
