EXAM PRACTICE QUESTIONS Chapter 17 1. Write the equilibrium constant expression for the following reaction. 2. Some nitrogen and hydrogen gases are pumped into an empty 5.00-L vessel at 500 ° C. When equilibrium was established, 3.00 moles of N 2 , 2.10 moles of H 2 , and 0.298 moles of NH 3 were present. Evaluate K c at 500 ° C. 3. The equilibrium constant, K c , for the following reaction is 0.0154 at a high temperature. A mixture in a container at this temperature has the concentrations: [H 2 ] = 1.11 M, [I 2 ] = 1.30 M and [HI] = 0.181 M. Will more product or more reactant be formed, or is the reaction at equilibrium? 4. K c = 0.040 for the system below at 450 ° C. If a reaction is initiated with 0.20 mole of Cl 2 , and 0.20 mole of PCl 3 in a 1.0-L container, what concentration of PCl 5 will be present at equilibrium? 5. Consider the equilibrium system below. Predict the affect on the equilibrium due to the application of each of the following stresses. A)
