Ammonia Synthesis Ammonia is synthesised via the reaction shown below: N2+3H22NH3 The molar Gibbs free energy of formation of ammonia at 298K and 1 bar is gf=16.5kJ/mol. (a) Find the Gibbs free energy of reaction at 298K and 1 bar. (b) Calculate the equilibrium constant at 298K and 1 bar. (c) Determine the equilibrium constant at 298K and 2 bar. (d) Calculate H and G from the standard molar enthalpies of formation and the standard molar entropies that can be found in the NIST Chemistry Web-book
