3. Ammonia is synthesised from the catalytic reaction of nitrogen and hydrogen: N2 + 3H2 = 2NH3 For this example, hydrogen is supplied at 50% excess. Table 3-1 and Table 3-2 below show the formation information and ammonia properties. For the Antione equation, psat is in bar and temperature is in K. Inpsat = A- B T+C Table 3-1: Formation Information (@ 298 K). Component Enthalpy of Formation Gibbs Energy of Formation kJ.molt kJ.mol-1 NH3 -46.11 -16.45 N2 0 0 H2 0 0 Table 3-2: Ammonia Properties.

(11 marks)
(b) It is necessary to optimise the reactor conditions in order to maximize the conversion. Clearly stating any assumptions made, evaluate the conversion at each of the following conditions: 0 600 K and 2 bar (abs). (1) 600 K and one other pressure of your choice. (ii) 2 bar (abs) and one other temperature of your choice. You must clearly explain why you have chosen the pressure and temperature chosen for parts (1) and (ii). (15 marks) (c) Based on your results in part (b), comment on the likely conditions that would optimise the production of ammonia. (2 marks) (d) Assuming the optimised reactor conditions are 500 K and 25 bar (abs), determine the Z-factor of ammonia using: (0) Virial equation truncated to two terms. (1) Soave-Redlich-Kwong Equation of State. Comment on your results. (12 marks)
