QUESTION 6 0,5mоl H2(g) аnd 0,6mоl Br2(g) is cоmbined in а 5.0dm3 flаsk and heated to 700 K. The reaction is exothermic : H2(g) + Br2(g) → 2HBr(g) 6.1 The concentration of HBr in the flask at equilibrium is 0.17 mol.dm-3. Calculate Kc. (8) 6.2 When the temperature is increased, will the Kc value INCREASE, DECREASE or STAY THE SAME? Use Le Chatelier's principle to explain your answer. (4) 6.3 Consider the following graph and answer the questions that follow: Right click on the following blue button to open the images for QUESTION 6, in a new tab. 6.3.1 Write a balanced equation that represents the exothermic reaction that takes place. (3) 6.3.2 Give the time (s) when the system reaches equilibrium. (2) 6.3.3 Name the disturbance that occurred at 14 s. (2) 6.3.4 How will the value of the equilibrium constant after this disturbance change? Write only INCREASE, DECREASE or STAY THE SAME. Give a reason for your answer. (3) 6.3.5 Name the conditions necessary for the reaction to reach equilibrium. (2) 6.3.6 Name one other condition that will affect the equilibrium in this reaction and explain what the effect will be on the Kc-value if this condition increases. (3) [27]
