Is it realistic to assume that there will be no CO in the tank when chemical equilibrium is reached? 1693 Using Henry's law, show that the dissolved gases in a liquid can be driven off by heating the liquid. Fundamentals of Engineering (FE) Exam Problems 1 2 O2 16100 If the equilibrium constant for the reaction H2 S H 2O is K, the equilibrium constant for the reaction 2H2O 2H2 O2 at the same temperature is (b) 1/(2K) (c) 2K (d) K 2 (e) 1/K 2 16101 If the equilibrium constant for the reaction CO 1 2 O2 S CO2 is K, the equilibrium constant for the reaction CO2 3N2 S CO 1 O2 3N2 at the same temperature is 2 (a) 1/K (b) 1/(K 3) (c) 4K (d) K (e) 1/K 2 (a) 1/K 822 | Thermodynamics 16108 The value of Henry's constant for CO2 gas dissolved in water at 290 K is 12.8 MPa. Consider water exposed to atmospheric air at 100 kPa that contains 3 percent CO2 by volume. Under phase equilibrium conditions, the mole fraction of CO2 gas dissolved in water at 290 K is (a) 2.3 (d) 2.2 10 10 4 4 16102 The equilibrium constant for the reaction H2 1 2 O2 S H 2O at 1 atm and 1500C is given to be K. Of the reactions given below, all at 1500C, the reaction that has a different equilibrium constant is (a) H 2 (b) 2H2 (c) H 2 (d) H 2 (e) H 2 1 2 O2 S H 2O 1 2 O2 at 5 atm at 1 atm at 2 atm 3N2 3N2 at 5 atm at 1 atm O2 2H2O O2 S H 2O 1 2 O2 1 2 O2 (b) 3.0 (e) 5.6 10 10 4 4 (c) 0.80 10 4 3N2 S H 2O 3N2 S H 2O 16109 The solubility of...
