CHEM1070 Review for the final exam 1 Final exam PPT 1 to 10 will be tested Not PPT 11 (Kinetics) PPT 6 to 10 (second half) is about 80 % Rest is about 20% One double-side A4 sheet of handwritten cheat notes allowed You have to prepare this on your own 3 The K c for the Haber Process, is 9.60 at 573 K. Suppose the equilibrium partial pressures for NH 3 and H 2 are 400. torr and 700. torr respectively. What is the equilibrium pressure for N2? = 700. torr = 0.933 bar K p = 4.23 × 10 -3 = = 82.7 bar (15.96) Consider the reaction: If you start with 25.0 mL of a 0.905 M solution of NaIO 4 , and then dilute it with water to 500.0 mL, what is the concentration of H 4 IO 6 - at equilibrium? 4 K c = 3.5 ×10 -2 (16.81) A solution of sodium acetate (CH 3 COONa) has a pH of 9.70. What is the molarity of the solution? (16.109) Butyric acid is responsible for the foul smell of rancid butter. The pK a of butyric acid is 4.84. (a) Calculate the pK b for the butyrate ion. (b) Calculate the pH of a 0.050 M solution of butyric acid. (c) Calculate the pH of a 0.050 M solution of sodium butyrate. 14.00 (17.53) Molar solubility of a saturated CaF 2 solution at 35°C is 1.24 × 10 -3 mol/L. (a) what is K sp at this temperature? (b) It is found that 1.1 × 10 -2 g SrF 2 dissolves per 100 mL of aqueous solution at 25 °C. Calculate the solubility product for SrF 2 . (c) The K sp of Ba(IO 3 ) 2 at 25°C is 6.0 × 10 -2 . What is the molar solubility of Ba(IO 3 ) 2 ? Continue.  #### You've reached the end of your free preview.
