Unformatted text preview: Chemistry 2080 Spring 2009 Problem Set #5 - due date: Friday, March 6th at 2 pm KEY Name:________________ Lab TA Name:__________________ Lab Day/Time:______________________ Practice problems (not graded). Chapter 15: 7, 11, 13, 15, 17, 29, 31, 33, 37, 39, 51 1) For each of the following reactions, calculate K p from K c In each case: K p = K c (RT) Δ n and at 25°C, RT = (0.08206 L.atm/mol.K)(298.15K) = 24.47 L.atm/mol (a) N 2 (g) + 3H 2 (g) 2NH 3 (g) K c = 3.5 x 10 8 at 25 °C Δ n = 2 – 4 = –2 ; so K p = K c (24.47) –2 = 5.8 x 10 5 atm –2 (b) 2H 2 (g) + O 2 (g) 2H 2 O(g) K c = 3.2 x 10 81 at 25 °C Δ n = 2 – 3 = –1 ; so K p = K c (24.47) –1 = 1.3 x 10 80 atm –1 (c) N 2 (g) + O 2 (g) 2NO(g) K c = 1.7 x 10 –3 at 2300 K Δ n = 2 – 2 = 0 ; so K p = K c = 1.7 x 10 –3 (d) 2NO 2 (g) N 2 O 4 (g) K c = 1.7 x 10 2 at 25 °C Δ n = 1 – 2 = –1 ; so K p = K c (24.47) –1 = 6.9 atm –1 2) One way to generate hydrogen gas is to react carbon monoxide with steam: CO(g) + H 2 O(g)...
