Less ammonia would be produced
The reaction would be faster
The reaction would be slower
More ammonia would be produced
- 9. Multiple Choice
What is the effect of increasing the pressure of a Haber process?
Equilibrium shifts to the left, more ammonia is produced
Equilibrium shifts to the left, less ammonia is produced
Equilibrium shifts to the right, more ammonia is produced
Equilibrium shifts to the right, less ammonia is produced

- 20. Multiple Choice22. Explain why only a moderately high temperature is used in industry for the production of Ammonia.a) Produces a lower % yield but at a faster rateb) Produces a higher % yield but at a faster ratec) Produces a lower % yield but at a slower rated) Produces a higher % yield but at a slower rate
- 21. Multiple Choice26. Once the Ammonia is separated from the Nitrogen and Hydrogen what is done with the spare Nitrogen and Hydrogen?a) The Hydrogen is sold as it is an expensive commodity and the Nitrogen is discarded.b) They are both recycled.c) The Nitrogen is is sold as it is an expensive commodity and the Hydrogen is discarded.d) Both are discarded as it is too expensive to separate them.
