A) Estimate the equilibrium composition of a mixture of 1.5 mol H2 and 0.5 mol of N2 to NH3 at 1 bar pressure at temperature of 298.15 K and 673.15K, using the assumption of ideal solution of ideal gases. ( The equilibrium constant K: 778 at 298.15K, 0.0137 at 673.15K) B) Modern large ammonia plants mostly carry out the ammonia production reaction at about 673.15 K and 150 atm pressure. Estimate the equilibrium composition at conditions of Problem 8-A, assuming that all reactants and products behave as ideal gases. C) Repeat Problem 8-B, taking into account the nonideal gas behavior of the reactants and produts with assumption of an ideal solution of nonideal gases. For this, use the below relationship taken by the Beattie-Bridgeman EOS. (0.1191849 91.87212 25122730 log P . T2 $(.) = + + 2730) 74 NH3 K ON 02 for T in K and P in atm
