Consider the following reaction at 25°C for which the following data are relevant: 2NO(g) + O2(g) → 2NO2(g) ΔH° = ‐114 kJ/mol ΔS° = ‐146 J mol‐1 K‐1
a) Sketch a ΔG° versus temperature graph.
b) Over what temperature range will this reaction be spontaneous under standard conditions at constant temperature and pressure?
