QUESTION 6 QUESTION 6 At high temperаtures аnd in the presence оf а catalyst, sulphur triоxide will decоmpose as in the following reaction: 2SO3(g) ⇄ 2SO2(g) + O2(g); ΔH = + 196 kJ.mol-1 In one experiment, 8,0 moles of sulphur trioxide was placed in a 12,0dm3 container and allowed to reach equilibrium. At temperature T1 there is 1,4 moles of oxygen in the equilibrium mixture. 6.1 Define a “reversible” reaction. (2) 6.2 Calculate the value of the equilibrium constant, Kc, by using the table method. (8) 6.3 The experiment is repeated at the same temperature, with the same amount of sulphur trioxide, but in a larger container. How will this affect the following? Write only INCREASE, DECREASE or STAY THE SAME. 6.3.1 The number of moles of oxygen in the new equilibrium mixture. (2) 6.3.2 The value of Kc. (1) 6.4 The experiment is repeated in the original container, but at a temperature of T2. The value of Kc is smaller than the value at T1. 6.4.1 Which temperature, T1 or T2 is the highest temperature? (1) 6.4.2 Explain your answer to Question 6.4.1 (3) 6.5 Write Le Chatelier's principle in words. (2) 6.6 Nitrogen gas and oxygen gas react in a closed container according to the reaction below: O2(g) + N2(g) ⇄ 2NO(g) After the reaction reaches equilibrium, certain changes are made. The graph represents the reaction rate versus time for the situation. 6.6.1 What does the space between the 10th and 15th minute represent? Define this phenomenon. (3) 6.6.2 A temperature change takes place at t = 15 minutes. Has the temperature increased or decreased? Explain your answer. (3) 6.6.3 Is the reverse reaction endothermic or exothermic? (1) 6.6.4 What change, other than the addition of a catalyst, may have occurred at t = 20 minutes? (1) 6.6.5 Explain how the change at t = 20 minutes affects the concentrations of each gas at equilibrium. (4) [31] Please do not submit any answers in the block below.
