Haber Process Flashcards
What are the reactants in the Haber process?
Nitrogen and Hydrogen
What are the products? (Haber process)
Ammonia
Show the full equation for the reaction. (Haber process)
N2 + 3H2 <=> 2NH3 (+ Heat)
List the conditions needed (for the Haber process)
450*C, 200 atmospherics.
Why is the Haber process important?
Ammonia produced can be used as nitrogen based fertiliser.
Where do we get nitrogen from? (Haber process)
Air
Where do we get hydrogen from? (Haber process)
Methane
Is it endothermic or exothermic? (Haber process)
Exothermic
How is ammonia removed? (Haber process)
Ammonia has a low boiling point, ammonia condenses into liquid ammonia.
What happens to the unused hydrogen and nitrogen?
The gaseous hydrogen and nitrogen are recycled back into the reactant mixture via a pipe at the top.
What 3 factors are important in this process? (Haber process)
Cost, Rate of Reaction and % Yield
Why can a lower temperature not be used? (Haber process)
Particles need plenty of kinetic energy in order to react.
Why can we not use a higher temperature? (Haber process)
Higher temperature cost is too expensive.
