Chemistry 2080 Spring 2010 Problem Set #6 - due date: Friday March 19th at 2 pm Name:________________ Lab TA Name:__________________ Lab Day/Time:______________________ 1) (a) Consider the following balanced chemical equation: 2NO(g) + Cl 2 (g) 2NOCl(g) K p = 0.27 at 700 K Suppose that a mixture of NO and Cl 2 is introduced into a reaction vessel at 700 K such that at the start of the reaction the partial pressure of the NO, (P NO ) is twice the partial pressure of the Cl 2 , (P Cl 2 ). Suppose further that when equilibrium is reached, the partial pressure of the NOCl product is 115 torr. What were the initial partial pressures of the NO and of the Cl

Unformatted text preview: 2 ? (b) Calculate the value of K c for the above reaction at 700 K. 2) A mixture of 0.0623 mol H 2 , 0.0414 mol I 2 , and 0.224 mol HI was placed in a 10.00 L stainless-steel flask at 430°C. The equilibrium constant K p for the reaction: H 2 (g) + I 2 (g) ∏ 2HI(g) is 54.3 at this temperature. (a) Calculate Q p for this reaction mixture, and say if the system is at equilibrium. If it is not at equilibrium, then say which direction this reaction will move. (b) Calculate the amounts in mols of H 2 , I 2 , and HI that will be present at equilibrium....
