Question 6 It is possible to make a breathing device by converting carbon dioxide into oxygen gas according to the following reaction: 4 KO,(s) + 2 co:(g) → 2 K,CO,(s) + 3 0,(g) How many grams of KO, (molar mass: 71.1 g/mol) are needed to produce 50.0 L of oxygen gas at 15 °C and 1.5 atm. Round your answer to 3 significant digits. g of KO, The equilibrium constant, K, for the reaction is 55.2 at 425°C. H,(g) + 1,(g) - 2HI(g) Question 7 A rigid cylinder at that temperature contains 0.127 atm of hydrogen, 0.134 atm of iodine, and 1.055 atm of hydrogen iodide. Is the system at equilibrium? Answer choices: a. Yes. b. No, the forward reaction must proceed to establish equilibrium. c. No, the reverse reaction must proceed to establish equilibrium. Your answer: Why?
