Type 3 11 In the reaction below, 2.55 atm each of H2 and Br2 were placed into a 1.00 L flask and allowed to react: H2(g) + Br2(g) <=> 2 HBr(g) Given that Kc = 29.8, calculate the equilibrium pressure of H2. Student Response Value Correct Answer Answer: .68 100% 0.68 Score: 1/1 2. Type 3 17 7In the reaction below, 5.39 atm each of Br2 and I2 were placed into a 1.00 L flask and allowed to react: Br2(g) + I2(g) <=> 2 IBr(g) Given that Kc = 22.3, calculate the equilibrium pressure of I2. Student Response Value Correct Answer Answer: 1.6 100% 1.60 Score: 1/1 3. Combining Equations 1 In combustion studies of the use of H2 as an alternative fuel, HO is sometimes formed in flames by the reaction, H(g) + 1/2 O2(g) <=> HO(g) Use the data below to calculate the value of Kc H2(g) <=> 2 H(g) Kc = 0.00128 1/2 H2(g) + 1/2 O2(g) <=> OH Kc = 0.642 Give your answer to 3 significant figures Student Response Value
