CHM 104 GENERAL CHEMISTRY II Introduction to Equilibrium Constants 1. Consider the following equilibrium: PCl 5(g) PCl 3(g) Cl 2(g) + At 500K, K c = 0.575, what is the value of K p ? 2. Consider the following equilibrium: 2 NO (g) Cl 2(g) 2 NOCl (g) + At 500K, the equilibrium pressures are P NO = 0.240 atm, P Cl2 = 0.608 atm and P NOCl = 1.35 atm. Calculate the value of K p and K c . 3. Consider the following equilibrium: SO 2 Cl 2(g) SO 2(g) Cl 2(g) + K p = 2.91 x 10 3 @ 298K If the equilibrium partial pressures of SO 2 and Cl 2 are 117 torr and 255 torr, respectively, what is the partial pressure of SO

Unformatted text preview: 2 Cl 2 ? 4. Again consider the equilibrium: SO 2 Cl 2(g) SO 2(g) Cl 2(g) + At a certain temperature, a reaction mixture is made containing an initial [SO 2 Cl 2 ] of 0.020 M. At equilibrium, [Cl 2 ] = 1.2 x 10-2 M. Calculate the value of K c at this temperature. 5. Consider the following equilibrium: 2 NO (g) 2 H 2(g) N 2(g) 2 H 2 O (g) + + A 100.0 mL reaction vessel initially contained 0.0260 mol NO and 0.0130 mol H 2 , at equilibrium, [NO] = 0.161 M. What is the value of K c ?...
