Consider the reaction of chlorine with nitric oxide below. K p = 6.5 x 10 -4 at 308 K. 2 NO( g ) + Cl 2 ( g ) 2 NOCl( g ) a) Write an equilibrium expression for the reaction in terms of partial pressures (i.e. P NO , etc.) b) If the reaction is at equilibrium at 308 K, are there more moles of product or of reactants? c) If you perturb the equilibrium by reducing the volume available, how will the reaction shift in response? d) If you set up the equilibrium by putting 1 bar of NOCl( g ) in a flask at 308 K and allowing it to react, what will the partial pressure of Cl 2 ( g ) be at equilibrium? 1. 2. Week 15 discussion problems Name _________________ In lab you explored the titration of the weak acid CH 3 COOH (acetic acid) with the strong base NaOH. The K a for CH 3 COOH is 1.8 x 10 -5 . a) Before you added any base, the CH 3 COOH in water dissociated according to its K a . Write a balanced chemical equation for CH 3 COOH dissociating in water. b)
