The reaction of nitrogen with oxygen under high pressure and temperature is a source of nitric oxide, NO, precursor to smog. Calculate ΔG° (in kJ) for the following reaction at 25°C:
N2(g) + O2(g) → 2NO(g) ΔHf°[NO(g)] = +90.4 kJ mol−1 ΔS° = 191.5 J mol−1 K−1 ΔS° = 205.0 J mol−1 K−1 ΔS° = 210.6 J mol−1 K−1
