Nitrogen dioxide gas undergoes decomposition producing nitrogen monoxide and oxygen gases: 2 NO2(g)........ 2 NO(g) + O2(g) A sample consisting of 0.10 moles of NO2 is placed in a 10.0 L in a container that is then heated to 750 K. When equilibrium is reached, the pressure in the container is 0.827 bar. Calculate the equilibrium constant and the degree of dissociation at this temperature. (Hint: pressures are directly proportional to concentration, so they can be used in ICE tables).

1. A sample of solid ammonium chloride was placed in an evacuated container and then heated so that it decomposed to ammonia gas and hydrogen chloride gas. After heating, the partial pressure of NH3 in the container was found to be 2.2 atm. Calculate Kp at this temperature for the decomposition reaction: NH4Cl (s) ⇄ NH3 (g) + HCl (g). 2. Consider the endothermic reaction Fe3+ (aq) + Cl¯ (aq) ⇄ FeCl2+ (aq). Use Le Châtelier’s principle to predict how...
