5. C3 REVISION – CHAPTER 5 – EQUILIBRIA KEY WORDS: Equilibrium Open/closed system Reversible Endothermic Exothermic Optimum conditions ASSESSMENT: Reversible Reactions Give an example of a reversible reaction – write the equation, remembering to include the reversible sign. What can you say about the energy change for the forward reaction when you compare it to the reverse reaction? Explain why an open system cannot reach equilibrium, whereas a closed system can. Explain the meaning of the term ‘position of equilibrium. The equilibrium strikes back! When conditions are changed in an equilibrium the system will respond to counteract these changes Explain how the position of equilibrium moves when you: i)Increase the temperature in a reaction where the forward reaction is endothermic ii)Increase the temperature in a reaction where the forward reaction is exothermic iii)Decrease the temperature in a reaction where the forward reaction is endothermic iv)Decrease the temperature in a reaction where the forward reaction is exothermic Under pressure! Explain how changing the pressure of a system effects the position of equilibrium in the following reaction: PCl 3 + Cl 2  PCl 5 Increase in pressure: Decrease in pressure: Explain why the Haber process is done at a very high pressure Explain why the Haber process is done at a ‘compromise’ temperature
