[Olympiad] For a specific reaction, ΔH = -100 kJ/mol and ΔS = -200 J/mol·K. Below what temperature (in Kelvin) will the reaction be spontaneous?
- 200 K
- 400 K
- 500 K
- 1000 K
📝 Batafsil tushuntirish
Spontaneity requires ΔG < 0. ΔG = ΔH - TΔS.-100,000 - T(-200) < 0
-100,000 + 200T < 0
200T < 100,000
T < 500 K.
