Haber Process Flashcards
what is a reversible reaction
a reaction where the direction can be changed by altering the conditions
what is a dynamic equilibrium
where the rate of forward reaction = the rate of backward reaction
what does the Haber process form
ammonia
what 3 reactants are needed for the haber process
nitrogen
hydrogen
where is the raw material of nitrogen gotten for the haber process
from the air
where is the raw material of hydrogen gotten for the haber process
from natural gas
what 3 conditions affect the rate of reaching an equilibrium
temperature
pressure
concentration
catalyst
how does increasing the temperature affect the position of equilibrium for a reaction
moves in the direction of the endothermic
how does increasing the pressure affect the position of equilibrium for a reaction
moves in the direction of the fewest gas molecules
how does increasing the concentration affect the position of equilibrium for a reaction
moves in the direction away from the increase in concentration
how does adding a catalyst the position of equilibrium for a reaction
no change
how does adding a catalyst affect the rate of reaching the equilibrium
rate increased
what 3 factors affect the industrial conditions for a process
- the availability of raw materials
- the control of temperature and pressure, many industrial processes are not allowed to reach equilibrium as it would take too long
- use of a catalyst
why is the haber process needed
to make fertilisers
what is in NPK fertilisers
Nitrogen
potassium
phosphorus
