CAIE A Level Chemistry 9701 · Equilibria
In a closed flask, iodine reacts reversibly with propanone to form an organic product. The forward reaction is exothermic. The system reaches dynamic equilibrium at a fixed temperature.
Suggest and explain how increasing the temperature of the flask affects the position of equilibrium and the value of the equilibrium constant, .
4 marks, so the mark scheme is looking for about 4 separate creditworthy points. Making the same point twice in different words earns it once.
Suggest means: Apply what you know to an unfamiliar situation. There may be more than one acceptable answer. Reason from the principle you have learned to the new context, and say which principle you are using.
