11 o I Review | Constants | Periodie Part A The following reaction is exothermic: 2SO2(g) + O2(g) = 2S03(g). What is the effect of increasing the temperature of the reaction mixture? You may want to reference (Pages 665 - 672) Section 15.9 while completing this problem. O The reaction shifts to the left. O The reaction shifts to the right. O Increasing the temperature does not cause any shift.

The elementary reaction 2 H,O(g) = 2 H,(g) + O,(g) proceeds at a certain temperature until the partial pressures of H,O, H, , and O, reach 0.061 bar, 0.0042 bar, and 0.0039 bar, respectively, at equilibrium. What is the value of the equilibrium constant at this temperature? Кр * TOOLS x10

2C02 2 2C0+0 Consider the reaction above. If pressure was increase on this equilibrium, how would that affect the amounts of reactants? O They would decrease O They would remain the same O They would increase

Part A It is possible to predict the equilibrium constant of a reaction by combining two or more reactions for which the value of K is known. When combining equilibrium constants, it is important to note the following: Determine the value of the equilibrium constant, Kpal, for the reaction • When a reaction is reversed, its K value is inverted; that is, Kreverse = 1/Kforward- • When the coefficients of a reaction are multiplied by a factor, the K value is raised to the power of that factor. • When reactions are added, their K values are multiplied. CO2 (g) = C(s) + 02(g). Kgoal =? by making use of the following information: 1. 2CO2 (g) + 2H20(1) = CH3COOH(1) + 202(g). K1 = 5.40 x 10-16 2. 2H2(g) + O2(g) = 2H,O(1). K2 = 1.06 x 1010 3. CH3COOH(1) = 2C(s) + 2H2(g) + O2(g). K3 = 2.68 x 10 9 Express your answer numerically. • View Available Hint(s) V ΑΣφ Kgoal = Submit Part B Determine the equilibrium constant, Kroal, for the reaction 4PCI, (g) = P4(s) + 10Cl2 (g), Kgoal =? by making use of…
