The Haber Process Flashcards
What is the Haber Process?
A reversible reaction between nitrogen and hydrogen to form ammonia.
Where is the nitrogen and hydrogen extracted from?
Nitrogen is extracted from the air.
Hydrogen is extracted from natural gas.
___________ and ____________ are pumped through _______.
nitrogen
hydrogen
pipes
The ___________ of the gas mixture is increased to _____ _______________.
pressure
200 atmospheres
The _____________ gases are heated to ____C and passed through a tank containing an __________________.
pressurised
450
iron catalyst
The mixture is ________ so the ammonia ____________, then it can be __________.
cooled
liquifies
removed
Why is unreacted hydrogen and nitrogen recycled in the last step of the Haber Process?
To save money and increase the effective overall yield.
Is the reaction of hydrogen and nitrogen in the Haber Process Endothermic or exothermic?
Exothermic.
What would happen to the percentage yield if the pressure was increased?
It would increase,
as higher pressures will encourage the reaction
which produces less volume.
What would happen to the rate of reaction if the temperature was increased?
It would decrease, since this is an exothermic reaction.
Will move to the left of the reaction.
