Repeat the calculations of Illustrations 13.4-1 and 13.4-2 for 50C. The Henrys law constant for ammonia in
Question:
Repeat the calculations of Illustrations 13.4-1 and 13.4-2 for 50°C. The Henry’s law constant for ammonia in water at this temperature is HHN3 = 384.5 kPa/mole fraction, and you can assume that the Henry’s constants for nitrogen and hydrogen are unchanged from the values given in Illustration 13.4-1.
One mole of nitrogen, 3 moles of hydrogen, and 5 moles of water are placed in a closed container maintained at 25°C and 13.33 kPa and, using the appropriate catalyst and stirring, allowed to attain phase and chemical equilibrium. Assuming that ammonia is formed by chemical reaction and that the liquid and vapor phases are ideal, compute the amount and composition of each phase at equilibrium (neglecting the aqueous-phase reaction of ammonia to form NH4OH, and its subsequent ionization). The following data are available:
(The Henry’s law constant for ammonia was computed from experimental data using the equation PNH3 = HNH3 xNH3 and assuming all of the ammonia absorbed to be present as NH3.)
