Unformatted text preview: of the liquid phase is 30 percent N2 and 70 percent O2. Chapter 16 1683 A constant-volume tank contains a mixture of 1 mol of H2 and 0.5 mol of O2 at 25C and 1 atm. The contents of the tank are ignited, and the final temperature and pressure in the tank are 2800 K and 5 atm, respectively. If the combustion gases consist of H2O, H2, and O2, determine (a) the equilibrium composition of the product gases and (b) the amount of heat transfer from the combustion chamber. Is it realistic to assume that no OH will be present in the equilibrium mixture? Answers: (a) 0.944H2O, 0.056H2, 0.028O2, (b) 132,574 J/mol H2 | 821 1694 Consider a glass of water in a room at 25C and 100 kPa. If the relative humidity in the room is 70 percent and the water and the air are in thermal equilibrium, determine (a) the mole fraction of the water vapor in the room air, (b) the mole fraction of the water vapor in the air adjacent to the water surface, and (c) the mole fraction of air in the water near the surface. 1695 Repeat Prob. 1694 for a relative humidity of 25 percent. 1696 A carbonated drink is fully charged with CO2 gas at 17C and 600 kPa such th...
