The Haber–Bosch fixation of dinitrogen for 1 atmosphere pressures of reactive species bond energies at 298.15 K for HH, NN, and NH3 are 436, 945, and 1173 kJ per mole, respectively. For ΔGo = −33 kJ mol−1 = −RTlnK, lnK = 13.3 and K = 105.78. K is the factor indicating the ratio of the forward transition species to the reverse.
