CHEMISTRY 1008 Name: _______________________ Homework Assignment #6 Due: Thursday, March 10 1. (2 pts) Consider the following reaction: 2 NO (g) + Br 2 (g) 2 NOBr (g) K p = 28.4 at 298 K In a reaction mixture at equilibrium, the partial pressure of NO is 118 torr and that of Br 2 is 176 torr. What is the partial pressure of NOBr in this mixture? 2. (8 pts) Carbon monoxide (CO) replaces oxygen (O 2 ) in oxygenated hemoglobin (Hb) according to the following reaction: HbO 2 (aq) + CO (aq) HbCO (aq) + O 2 (aq) (a) Use the following reactions and associated equilibrium constants at body temperature to find

Unformatted text preview: the equilibrium constant for the above reaction. (i) Hb (aq) + O 2 (aq) ↔ HbO 2 (aq) Kc = 1.8 (ii) Hb (aq) + CO (aq) ↔ HbCO (aq) Kc = 306 (b) Suppose that an air mixture become polluted with carbon monoxide at a level of 0.10%. Assuming the air contains 20.0% oxygen, and that the oxygen and carbon monoxide ratios that dissolve in the blood are identical to the ratios in the air, what would be the ratio of HbCO to HbO 2 in the bloodstream?...
