1) Mixture of ethylene (1), propylene (2) and ethane (3) were withdrawn from a distillation column as a top product. The distillation column was operated at 150°C and 30 bar. Mole fraction of ethylene, propylene and ethane at the distillate are 0.35, 0.5 and 0.15, respectively. Determine fugacity and fugacity coefficient for all components.

2) A gas mixture containing 2 moles of nitrogen, 7 moles hydrogen and 1 mole of ammonia initially is undergoing the following reaction:

N2 +3H2 →2NH3

a) Derive an expressions for mole fractions of various components in the reaction mixture in terms of the reaction coordinate.

b) Explain how the conversion of limiting reactant is related to the extent of reaction.

c) The standard heat of formation and standard free energy of formation of ammonia at 298 K are -46100 J/mol and -16500 J/mol respectively. Calculate the equilibrium constant for the above reaction at 500 K. (Assume, the standard heat of reaction is constant in the temperature range of 298 to 500 K). Determine, whether the reaction is endothermic or exothermic.

d) For ammonia synthesis, the temperature and pressure of the reaction are 500 K and 20 bar. Determine the fractional conversion of nitrogen to ammonia at this temperature and pressure.

e) If two moles of Argon is added to the system and the conditions are same as in (d). Determine the effect of Argon on fractional conversion of nitrogen.
