For a given reaction, if ΔH = 35.5 kJ/mol and ΔS = 83.6 J/K·mol, at what temperature is the reaction spontaneous?
(Assume ΔH and ΔS remain constant with temperature.)
1. | T < 425 K | 2. | T > 425 K |
3. | All temperatures | 4. | T > 298 K |
For a given reaction, ∆H = 35.5 kJ mol–1 and ∆S = 83.6 J K–1 mol–1. The reaction is spontaneous at:
(Assume that ∆H and ∆S do not vary with temperature)
1. T > 425K
2. All temperatures
3. T > 298K
4. T < 425K
The correct thermodynamic conditions for the spontaneous reaction at all temperatures is
