Ammonia, NH₃, is produced from its elements in the industrial Haber process. Calculate ∆H°, ∆G°, and ∆S° at 25°C. See Appendix C for data. The industrial process is run at temperatures around 450°C. Would the equilibrium yield be more or less at 25°C? Explain. Estimate the equilibrium constant K_p at 450°C.
