The industrial synthesis of ammonia has the form: 1/2 N2 ( g) + 3/2 H2 (g) → NH3 (g) . Calculate the standard Gibbs energy change and equilibrium constant for the industrial synthesis of ammonia. Determine the equilibrium constant for the industrial synthesis of ammonia at 400 K.

[Hint: The tabulated enthalpy and Gibbs free energy of formation of ammonia are ΔH f 0 (NH3 ) = - 45.9 kJ/mol and ΔGf 0 (NH3 ) -16.5 kJ/mol, respectively. You may also assume the enthalpy is constant with temperature]
