Equilibrium Diagram for Air–NH₃–H₂ at 20^oC and 1 atm.
The partial pressure of ammonia (A) in air–ammonia mixtures in equilibrium with their aqueous solutions at 20^oC is given in Table 4.7. Using these data, and neglecting the vapor pressure of water and the solubility of air in water, construct an equilibrium diagram at 101 kPa using mole ratios Y_A = mol NH₃/mol air and X_A = mol NH₃/mol H₂O as coordinates. Henceforth, the subscript A is dropped. If 10 mol of gas of Y = 0.3 are contacted with 10 mol of solution of X= 0.1,what are the compositions of the resulting phases? The process is assumed to be isothermal at 1 atm.
