Answer: 3 1665 In absorption refrigeration systems, a two-phase equilibrium mixture of liquid ammonia (NH3) and water (H2O) is frequently used. Consider a liquidvapor mixture of ammonia and water in equilibrium at 30C. If the composition of the liquid phase is 60 percent NH3 and 40 percent H2O by mole numbers, determine the composition of the vapor phase of this mixture. Saturation pressure of NH3 at 30C is 1167.4 kPa. 1666 Consider a liquidvapor mixture of ammonia and water in equilibrium at 25C. If the composition of the liquid phase is 50 percent NH3 and 50 percent H2O by mole numbers, determine the composition of the vapor phase of this mixture. Saturation pressure of NH3 at 25C is 1003.5 kPa. Answers: 0.31 percent, 99.69 percent Review Problems 1677 Using the Gibbs function data, determine the equilibrium constant KP for the dissociation process O2 2O at 2000 K. Compare your result with the KP value listed in Table A28. Answer: 4.4 10 7 1678 A mixture of 1 mol of H2 and 1 mol of Ar is heated at a constant pressure of 1 a...
