Type 3 4 In the reaction below, 4.48 atm each of H 2 and Cl 2 were placed into a 1.00 L flask and allowed to react: H 2 (g) + Cl 2 (g) <=> 2 HCl(g) Given that Kc = 77.6, calculate the equilibrium pressure of HCl. Student Response Value Correct Answer Answer not answered 0% 7.30 Score: 0/1 2. Type 3 10 In the reaction below, 4.16 atm each of H 2 and Cl 2 were placed into a 1.00 L flask and allowed to react: H 2 (g) + Cl 2 (g) <=> 2 HCl(g) Given that Kc = 25.7, calculate the equilibrium pressure of Cl 2 . Student Response Value Correct Answer Answer not answered 0% 1.18 Score: 0/1 3. Combining Equations 2 Hydrocarbons are often reacted with steam to form H 2 , as shown for propane: C 3 H 8 (g) + 6 H 2 O(g) <=> 3 CO 2 (g) + 10 H 2 (g) Calculate K p for this reaction at a particular temperature, given: 3 CO(g) + 7 H 2 (g) <=> C 3 H 8 (g) + 3 H 2 O(g) K p = 7.10 x 10 13 at this temperature CO(g) + H 2 O(g) <=> CO 2 (g) + H 2 (g) K p = 0.296 at this temperature
