Predict whether each of the following reactions will be spontaneous at all temperatures, nonspontaneous at all temperatures, spontaneous at low temperatures, or spontaneous at high temperatures. (a) N2(l) + O2(g) ? 2NO(g) ?Ho = 180.7 kJ (b) P4(g) + 6Cl2(g) ? 4 PCl3(g) endothermic (c) 2H2O(g) + 2Cl2(g) ? 4HCl(g) + O2(g) ?Ho = -114.4 kJ
