The vapor pressure of pure water at 25C is 23.8 torr. What is the vapor pressure (in torr) of water above a solution of 18 g of glucose (nonelectrolyte, MW 180 g/mol) in 95 g of water (MW 18 g/mol)? (a) 24.3 (b) 23.4 (c) 0.451 (d) 0.443 (e) 23.8 Acetic acid, HCH302, has a pK: of 4.74. If one has 1.00 L of a 0.100 M solution of acetic acid, how many moles of solid NaOH would be added to give a pH of 4.90? (a) 0.059 (b) 0.100 (c) 0.144 (d) 0.050 (e) 0.041 Consider the Haber process for ammonia: 1/2 N(g) + 3/2 H(g) NH3(g) The reaction is catalyzed by iron metal. Which of the following could a chemical engineer recommend to management to increase the equilibrium amount of ammonia? (i) increase the size of the reaction vessel (ii) increase the temperature of the process. (iii) increase the amount of iron catalyst AH-46.1 kJ/mol, AS = -99 J/K-mol
