Equilibria Quiz

1. 1What is meant by the term 'closed system'?

2. 2What can be said about the rate of forward reaction and backwards reaction when a reversible reaction has reached equilibrium?

   1. AThey are the equal
   2. BThey occur at the same rate
   3. CThe occur at different rates
3. 3If the forward reaction is endothermic in a reversible reaction, the backwards reaction must also be endothermic.

   1. AVerdadero

4. 4What would be the effect of decreasing the temperature on this reaction?

   

   1. AThe equilibrium position would stay the same
   2. BThe equilibrium position would shift right

   1. AThe equilibrium position would stay the same
   2. BThe equilibrium position would shift left
   3. CThe equilibrium position would shift right
6. 6What would happen if the concentration of the products was increased?

   

   1. AThe equilibrium would be disrupted and the system starts to form more reactants until equilibrium is reached again
   2. BThe equilibrium would be disrupted and the system starts to form more products until equilibrium is reached again
   3. CNothing
7. 7What is the source of nitrogen used in the Haber Process?

   1. A2
   2. B3
10. 10The Haber Process uses an iron catalyst which means the equilibrium is achieved sooner but the position is unaffected

    1. AVerdadero
    2. BFalso

11. 11Nowadays ammonia is used to produce what?

    1. APetrol
    2. BFertilisers
    3. CA raising agent in cakes
12. 12What temperature is the Haber Process performed at?

    1. A100 oC
    2. B500 oC
    3. C450 oC
13. 13The [blank_start]Haber Process[blank_end] is performed at [blank_start]450[blank_end] oC which is high enough to have a high [blank_start]rate or reaction[blank_end] but low enough to encourage the [blank_start]exothermic[blank_end] reaction.

    1. AHaber Process
    2. BHelix Process
    3. CHaber Test
    4. D450
    5. E500

    7. Grate of reaction
    8. Hyield
    9. Iatom economy
    10. Jexothermic
    11. Kendothermic
14. 14What pressure is the Haber Process performed at?

    1. A200 atm
    2. B100 atm
    3. C400 atm
15. 15The Haber Process is performed at [blank_start]200[blank_end] atm which is high enough to encourage [blank_start]ammonia[blank_end] production (fewer [blank_start]gas[blank_end] molecules) but [blank_start]cheaper[blank_end] as it doesn't need to withstand high [blank_start]pressure[blank_end].

    1. A200
    2. B100
    3. C400
    4. DAmmonia
    5. ENitrogen

    1. AReleased into the atmosphere
    2. BPut through the process again
    3. CDestroyed
17. 17How is ammonia removed from the industrial process?

    

    1. AEvapourated
    2. BCooled and condensed
    3. CSolidified
18. 18What would be the effect of increasing the temperature on this reaction?

    

    1. AThe equilibrium position would shift to the right
    2. BThe equilibrium position would shift to the left
    3. CThe equilibrium position would stay the same
19. 19What would be the effect of decreasing the pressure on the reaction?

    

    1. AThe equilibrium position would shift to the left
    2. BThe equilibrium position would shift to the right
    3. CThe equilibrium position would stay the same
20. 20What would happen if the concentration of the reactants increased?

    

    1. AThe equilibrium would be disrupted and the system starts to form more reactants until equilibrium is reached again
    2. BThe equilibrium would be disrupted and the system starts to form more products until equilibrium is reached again
    3. CNothing
