1 Chemistry 2090 Problem Set #7 Due Monday (in class), March 14, 2011 Read Chapter 19 Chap 17 problems: 46, 48 Chap 19 problems: 10, 17, 26, 28, 35, 36, 38, 54, 60 Ex3. As we saw in exam 1 ('10), butyraldehyde, H 3 CCH 2 CH 2 (C=O)H, is made in the hydroformylation reaction from CO, H 2 and propene (H 3 CCH=CH 2 ). H 3 CCH=CH 2 (g) + CO (g) + H 2 (g) ______ > H 3 CCH 2 CH 2 (C=O)H (l) H f ° (KJ/mol) 20.4 -110.5 -245.4 S° (J/K . mol) 260 198 131 243 a. What is the G f ° change for this process (298 K)? b. What is the equilibrium constant, K p , for this reaction assuming the standard state of the

Unformatted text preview: butyraldehyde is a liquid (i.e., neglect its vapor pressure). c. Write an expression for the partial pressure of CO at 298 K given your answer in b. d. The hydroformylation reaction is usually conducted at 200C (Celsius). What is the equilibrium constant, K p , at this temperature? e. A typical set of starting conditions is p propene = p CO = p H2 = 100 atm. When the reaction achieves equilibrium at 200C, what are the final pressures of propene, CO and H 2 ? f. What is K c for the hydroformylation reaction at 200C?...
