6 problems on ΔG = ΔH - TΔS. Q1: 'ΔH = -100 kJ/mol, ΔS = +200 J/mol/K, T = 300K. ΔG = -100 - (300)(0.200) = ___ kJ/mol' (-160, spontaneous). Q2: 'ΔH = +50 kJ/mol, ΔS = +100 J/mol/K. T where ΔG = 0: T = ΔH/ΔS = ___ K' (500K). Q3: 'From Q2: Is the reaction spontaneous at 600K?' (Yes - T > 500K → ΔG <
