Answer the questions below by circling the number of the correct response Base your answers to questions 1 through 3 on the following system at 8. Given the reaction at equilibrium: 2SO2(g) + O2(g) - 2503(g), if equilibrium: the temperature remains constant, an increase in pressure will 2012(g) + 2H2O(g) - 4HCl(g) + O2(9) AH = +27 kcal. (1) have no effect on the equilibrium (2) shift the equilibrium to the right 1. If the temperature of the system is increased at a constant (3) shift the equilibrium to the left pressure, the rate of the forward reaction will (4) change the value of the equilibrium constant (1) decrease (3) remain the same (2) increase (4) decrease then increase 9. Given the reversible reaction Alg) +B(g) - C(g) at equilibrium. If the concentration of A is increased at constant temperature and 2. If Oz is added to the system at a constant pressure and pressure, which will also increase? temperature, the number of moles of HCl will (1) the rate of the forward reaction (1) decrease (3) remain the same (2) the value of the equilibrium constant (2) increase (4) decrease then increase (3) the activation energy (4) the concentration of B 3. If the pressure on the system is increased at a constant temperature, the value of the equilibrium constant for the reaction 10. Given the reaction at equilibrium: 2802(9) + O2 = 2803 +47 will kcal, the amount of SO3(9) will increase if there is (1) decrease (3) remain the same (1) an increase in temperature (2) increase (4) decrease then increase (2) a decrease in pressure (3) an increase in concentration of SO2(g) 4. In the equilibrium reaction: Alg) + 2B(g) + heat =AB2(9), the rate (4) a decrease in concentration of O2() of the forward reaction will increase if there is (1) an increase in pressure of the reaction vessel 11. Given the reaction at equilibrium: 2AB(9) + heat = A (9) + B (9) (2) a decrease in temperature the equilibrium will shift to the right when the (3) an increase in the volume (1) temperature increases (3) pressure increases (4) a decrease in the concentration of Alg) (2) temperature decreases (4) pressure decreases 5. For a given system at equilibrium, lowering the temperature will 12. Given the reaction at equilibrium: N2(g) + 3H2(g) = 2NH3(9) always heat, which change will increase the amount of NH3(g) in the (1) increase the rate of reaction system? 2) increase the concentration of products (1) an increase in the concentration of N2(9) (3) favor the exothermic reaction (2) an increase in temperature (4) favor the endothermic reaction (3) a decrease in pressure (4) a decrease in the concentration of H2(9) 6. Given the equation AgCl(s) - Ag+ (aq) + Chaq). As NaCl(s) dissolves in the solution, the Ag*(aq) concentration will (1) decrease as the amount of AgCl(s) decreases (2) decreases as the amount of AgCl(s) increases (3) increases as the amount of AgCl(s) decreases (4) increases as the amount of AgCl(s) increases 7. Equilibrium is reached in all reversible chemical reactions when the (1) forward reaction stops (2) reverse reaction stops (3) concentrations of reactants and the products become equal (4) rates of the opposing reactions become equal
