What is the equilibrium constant, K, value (ignore units) at 441.3 K for the following reaction ? N2(g) + 3 H2(g) ? 2 NH3(g) [Note (all at 25oC): (1) Standard enthalpies of formation for N2, H2, and NH3, are, respectively, 0, 0, and -46.10 kJ/mol. (2) Standard free energies of formation for N2, H2, and NH3, are, respectively, 0, 0, and -16.50 kJ/mol. (3) Standard entropies for N2, H2, and NH3, are, respectively, 191.5, 130.6, and 192.3 J/(mol·K).]
